The illustrations of the axially symmetric paper-cutting tutorial are as follows:

1. Fold the square material diagonally once.

2. Find the middle point of the material and divide the plane into three parts. Fold one part upwards and the other corner part backwards.

3. Flatten the material and then fold it in half.

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

5. Cut off the part marked by the slash.

6. The symmetry axis paper cutting is completed.

1. Definition of axially symmetrical figures

Axisymmetrical figures refer to figures in which a figure is folded along a straight line in a plane, and the parts on both sides of the straight line can completely overlap.

The straight line is called the axis of symmetry (axisofsymmetric), and the symmetry axis is represented by a dotted line; at this time, we also say that the figure is symmetrical about this straight line. Such as circles, squares, isosceles triangles, equilateral triangles, isosceles trapezoids, etc.

2. Example

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

The second step is to fold the prepared paper in half.

The third step is to rotate the folded paper opening to the right.

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

The fifth step is to draw the legs of the spider.

The sixth step is to draw the lines of the spider inside the body.

The seventh step is to take out the scissors and cut out the drawn spider.

The eighth step is to unfold the cut out spider.
