Axisymmetric figure, a mathematical term, is defined as a figure folded along a straight line in a plane, and the parts on both sides of the straight line can completely overlap.

A straight line is called the axis of symmetry, and the axis of symmetry is represented by a 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.

Axisymmetric graphics must be folded along a straight line, and the parts on both sides of the straight line overlap each other. The key is to grasp two points: one is to fold along a straight line, and the other is to overlap each other.
