Embodiment 1
[0070] Example 1: Flower shape
[0071] Such as figure 1 As shown, the flower shape is folded out of triangles in the basic shape, and the specific folding steps are as follows;
[0072] a. First fold the circle into a square in the basic shape;
[0073] b. Fold the square in half along the diagonal to form an isosceles triangle, in which the side with the arc side is invisible;
[0074] c. Pass the center point of the bottom side of the isosceles triangle, draw two straight lines to the place where the waist distance is less than one-half of the bottom side, and fold the two bottom corners of the triangle along the two straight lines, forming three tips at the upper end , Which represents the petals of the flower;
[0075] d. Fold back the other three corners except for the three tips of the petals to form a flower bone shape.
Embodiment 2
[0076] Example 2: Straight-edge grass
[0077] Such as figure 2 As shown, the folding steps of straight-edge grass are as follows:
[0078] a. Fold the circle into a square in the basic shape;
[0079] b. Pass a vertex of the square, draw two straight lines to the two sides of the opposite vertex, fold the two wings outside the two straight lines into the square along the two straight lines, and fold the two sides of the original square The connecting lines of the two vertices overlap to form a symmetrical figure along the connecting axis of the two vertices, the figure is a gyro cone with a large end and a small end;
[0080] c. Draw two straight lines from the vertex of the big end of the top cone to the two sides of the opposite vertex, and fold the two wings outside the two straight lines in half along the two straight lines, and fold the two sides of the vertex of the big end. , Which coincides with the line connecting the big end vertex and the small end vertex, forming a rhom...
Embodiment 3
[0083] Example 3: Curvy grass
[0084] Such as image 3 As shown, the folding steps of the curved grass shape are as follows:
[0085] a. Fold the circle into a square in the basic shape;
[0086] b. Fold the square in half along the diagonal to form an isosceles triangle, where the side with the arc side is visible outwards;
[0087] c. Pass the apex of the isosceles triangle, draw a straight line to any point on the bottom side except the midpoint, and fold the isosceles triangle along the straight line to form a shape with an external obtuse angle and three acute angles;
[0088] d. Pass a point on the straight line introduced in step c, draw two straight lines to the two vertices of the base of the original isosceles triangle, and fold the obtuse angle inward.
