The principle of axial symmetry is to fold the graph along a straight line. If it can overlap with another figure, then it is said that the two figures are symmetrical about this line, which is called the symmetry axis, and the point where they overlap after folding is the corresponding point, which is called the symmetry point. Axisymmetric graphics and axisymmetric graphics have the same characteristics, and the corresponding points have the same distance from the axis of symmetry.

Using axisymmetrical scissors, we can find the relationship between the number of folds and the number of villains, so as to better understand the axisymmetrical principle.
