The practice of inscribed a circle with a regular pentagonal pentagonal star
1. The drawing steps of a circle inscribed regular pentagon and a five-pointed star are as follows: Draw the circle inscribed regular pentagon to determine the center and radius. Let the center of a given circle be O and the radius is OA. Draw an arc with A as the center of the circle and OA as the radius, intersect the circles at points B and C, connect B and C, and obtain the chord BC related to OA. This step is used to assist in subsequent midpoint positioning.
2. Method 1: Draw the basic circle and diameter based on the pentagonal pentagonal structure to make circle O, mark the center of circle O, and make a horizontal diameter AM. This diameter will serve as a baseline for subsequent construction. Determine the vertical radius and midpoint so that the radius ON is perpendicular to AM and intersects point N. Take the midpoint K of ON (OK = KN), which is used for subsequent radius calculations. Calculate the side length of a regular pentagon with K as the center and KA as the radius and draw an arc, intersecting OM at point H.
3. Method 1: First draw a circle with a compass on paper, and then draw two mutually perpendicular diameters AC and BD of the circle. Next, with C and D as the center of the circle, draw an arc with the radius of diameter BD. The two arcs intersect at point E. OE is approximately equal to the side length of the inscribed regular pentagon of the circle. Starting from point A, cut four points in turn on the circumference with OE as the radius and connect two adjacent points, so that the inscribed regular pentagon of the circle can be obtained.
4. The standard ruler and gauge construction method of a circle inscribed with a regular pentagon is used to draw the diameter and vertical bisector based on the center of the circle O, and use a ruler to determine the diameter AB of the circle. Subsequently, use a compass to draw an arc with the midpoint of AB as the center of the circle and a radius slightly larger than half of the length of AB. The circles intersect at points C and D, and connect the CD to form the perpendicular bisector of AB. At this time, the intersection of CD and AB is the center of the circle O, and CD divides the circle into two parts that are symmetrical up and down.
5. Draw a horizontal straight line of 4CM on the paper, and point a point at the middle two centimeters. Other size can be increased or decreased according to proportion, as shown below. Draw a 3CM straight line perpendicular to it in the middle of the horizontal line, and 5CM above and below, as shown below. Use a 4CM straight line to connect the left line and the center line, as shown below. Use a 4CM straight line to connect the right line and the center line, as shown below.
6. Make a diameter AB, and then make a diameter CD perpendicular to it. Make the midpoint E of OB and connect ED. Make a circle with E as the center of the circle, ED as the radius, and the radius AO intersect F. Connect FD, first take D as the center of the circle and DF as the radius, and intercept them in turn on the circle to get five points. Connecting the five points intercepted on the circle results in a regular pentagon inside the circle. Then connect the line from the inner corner of the pentagon to get a regular pentagram.
How to do holding a pentagram
1. The easiest method is to first draw a regular pentagon, connect the corners with straight lines and erase the original pentagon, or extend the sides of the regular pentagon to intersect to form a larger five-pointed outline. Personnel positioning: Arrange some personnel to stand at the apex and corner points, holding fans as the "skeleton" of the five-pointed star. The remaining personnel fill the free area inside the five-pointed star and enhance the overall visual effect by adjusting the fan orientation (such as uniformly facing outwards or inwards).
2. The five-pointed star method is as follows: three square pieces of paper need to be prepared, of the same size. After folding everything diagonally, press hard on the folded edges with your nails.
3. Shape arrangement: Adjust the five sharp corners of the five-pointed star to expand symmetrically to complete the three-dimensional shape. Advantages: The single component is easy to fold and has a strong three-dimensional effect after being bonded, making it suitable for hanging or holding as a performance prop; the use of colored paper of different colors can enhance the visual effect. Notes: The glue should be applied evenly to avoid spillage; keep the angle of the parts consistent when adhering to prevent the five-pointed star from being distorted.
4. The professional tutorial for origami of five-pointed stars is as follows: Prepare a rectangular piece of paper (for easier operation, you can cut it into a long piece of paper one centimeter wide in advance). Starting action for basic steps: Hold one end of the paper strip and wrap the paper strip with your index finger so that one end of the paper strip is wrapped in the loop. Fold for the first time: Now the long end of the paper is on the right hand side, fold it along the edge to the upper left to form an angle.
5. Surface decoration: Sequins, buttons or embroidery patterns can be sewn on the surface of the five-pointed star to increase the visual effect. If a crocheted frame is used, the crocheted edge can be turned out to form a double decorative effect. Structural reinforcement: If the five-pointed star is large, horizontal or longitudinal cloth strips can be sewn inside to enhance stability. If a rope knot or twist bar skeleton is used, check whether the junction is firm and reinforce it with wire if necessary.
6. Fold three-dimensional stars Take a piece of star paper and fold it diagonally into a five-pointed star shape. The specific steps are: tie one end of the paper strip, flatten it and form a prototype of the five-pointed star, then thread the remaining paper strip into the five corners of the five-pointed star in turn, gradually tighten and adjust the shape, and finally cut off the excess part and fix the end. When folding, it is necessary to keep the tension of the paper strip even to avoid deformation of stars. It is recommended to fold 10-15 stars in advance to meet the bouquet decoration needs.
The practice of five-pointed stars
The following are three simple ways to make a five-pointed star: Method 1: Square paper folding and shearing method (classic model) Materials: square paper, scissors.
There are the following ways to use red five-pointed stars: Origami method: Flat five-pointed stars: Use a piece of square paper, fold the sides first, and then fold it diagonally on the left, and a center point will appear. Then use the lower right corner to coincide with this center point once. After turning it over, make the two sides coincide and align them. Following this step, you can fold a flat five-pointed star.
The steps for drawing a circle inscribed regular pentagon and a five-pointed star are as follows: Draw a circle inscribed regular pentagon to determine the center and radius. Let the center of a given circle be O and the radius is OA. Draw an arc with A as the center of the circle and OA as the radius, intersect the circles at points B and C, connect B and C, and obtain the chord BC related to OA. This step is used to assist in subsequent midpoint positioning.
The method for using a five-pointed star is as follows: Fold the paper in half: First fold the paper in half from the middle to ensure that the two sides completely overlap. Measure and fold at a 72-degree angle: Measure approximately 72-degree position on the paper. Fold it in half from the measured position in the direction shown by the arrow to form an included angle of 72 degrees. Fold the remaining angle: The remaining angle is about 36 degrees. Fold the 36-degree angle in the opposite direction from the position shown by the corresponding red line to make it fit smoothly.
What are the practices of red pentagram
1. There are the following ways to use red five-pointed stars: Origami method: Flat five-pointed stars: Use a piece of square paper, fold the sides first, and then fold it diagonally on the left, and a center point will appear. Then use the lower right corner to coincide with this center point once. After turning it over, make the two sides coincide and align them. Following this step, you can fold a flat five-pointed star.
2. There are two main methods to make red five-pointed stars: origami and paper-cutting. Origami method: Preparation materials: 5 pieces of square red colored paper with a side length of 5 centimeters are needed. Folding steps: Fold each piece of colored paper according to specific steps to form a five-pointed star unit. This includes steps such as diagonal folding, folding the whole body up and down, and pressing specific creases to ensure that each unit accurately presents the shape of a five-pointed star.
3. Method 1: Rice crease cutting method Basic folding: Take yellow square paper, fold the "rice" shape trace along the diagonal line and the middle point of the opposite side, and then fold it in half into a triangle. Align the vertices of the triangle with the intersection and fold it again to form a smaller triangle.

Method 1: Basic five-pointed star cutting method Paper preparation and initial folding Take a square piece of paper and fold it in half along the diagonal line to form a triangle. At this time, the paper is divided into left and right parts. Mark the midpoint and double fold to mark the midpoint of the left half of the triangle (you can use visual inspection or folding in half to assist in positioning), and then fold the lower right corner towards the midpoint of the left half so that the lower right corner coincides with the midpoint.
There are many ways to cut paper flowers and five-pointed stars. The following are the steps of two methods: Method 1: Prepare materials: Prepare a square piece of red paper. Fold the corners in half: Fold the two opposite corners of the paper in half to ensure that the edges are aligned. Fold in half in the middle: Fold the upper triangular part in half in half in the lower middle, and then open it to form a one-word mark. Fold the sides in half: Fold the lower right corner to the left, fold the horizontal point flat, and then fold the entire paper in half.
Here are three easiest ways to cut five-pointed stars: Plan 1: Basic folding method (suitable for beginners) Tools required: square colored paper, scissors, and pencils. Step: Fold the paper: Fold the square paper in half along a diagonal line to form a triangle, and then fold it in half along another diagonal line to form a smaller triangle. When unfolded, it will leave a cross crease. Marking and drawing: Mark two points at 1/5 of the bottom edge of the triangle, and connect these two points to form the outline of a five-pointed star.
The easiest way to make a five-pointed star
Method 1: Square paper folding and shearing method (classic model) Material: square paper, scissors. Steps: First fold the square paper diagonally into an isosceles right triangle; then fold in half at sharp angles on both sides, press a crease at the midpoint of the bottom edge and unfold; then fold the midpoint of the bottom edge to one-third of the left waist to form a symmetrical angle; Finally, fold two equal corners, mark the diagonal lines with a pencil, cut them along the line, and unfold to get the five-pointed star.
Folding a five-pointed star with a straw can be achieved through the following steps, and three methods are combined to compile a general operating process: Method 1: Pretreat the straw with basic folding method: Pull the straw flat at about 1 cm at one end, and fold it in half along the center line to form a right-angle crease. Clear indentations can be seen after unfolding.
Preparation of materials and preliminary folding: Prepare a piece of paper with a width of 5 centimeters. There are two folding methods for the five-pointed star. The first is to tie a knot on the edge of the paper to strengthen the crease, and then fold it in half along the edge of the five-pointed star, and then fold it in half again.
Paper-cutting method: Prepare a 20*20 square red colored paper, fold it diagonally first, fold it with a double triangle to the middle, and then fold the right corner to the left crease point. Then fold the triangle and fold it in half again. Draw a triangle at the bottom, draw a parallel line about 0.2 cm at the top, then draw the shaded part and cut out the marked part. Finally, cut the upper end horizontally to get a simple and beautiful paper-cut five-pointed star.
