Solution of axisymmetric paper-cutting process

Axisymmetric paper-cutting tutorial is illustrated as follows:

1, the square material is folded diagonally once.

2. Find out that the midpoint plane of the material is divided into three parts, one part is folded up and the other part is folded back.

3. flatten the material and then flatten it in half.

4. Draw a pattern with symmetry axis and mark the points to be cut off.

5. Cut off the parts marked with diagonal lines.

6. Symmetry axis paper cutting is completed.

First, the definition of axisymmetric figure

Axisymmetric figure refers to a figure folded along a straight line in a plane, and the parts on both sides of the straight line can completely overlap.

Among them, the straight line is called the symmetry axis, and the symmetry axis is represented by the dotted line; At this time, we also say that this figure is symmetrical about this line. Such as circle, square, isosceles triangle, equilateral triangle, isosceles trapezoid, etc.

Second, examples

The first step is to prepare tools and materials to be used.

Step 2: Fold the prepared paper in half.

Step 3, rotate the folded paper opening to the right.

Step 4: Take out the pen and draw the body part of the spider.

Step five, then draw the feet of some spiders.

Step 6, then draw the spider's lines in the body.

Step 7, take out the scissors and cut off the painted spider.

Step 8, finally unfold the cut spider.
