In a plane, a figure is folded along a straight line, and the parts on both sides of the straight line can completely overlap. Axisymmetric graphics, also known as axisymmetric graphics or symmetric graphics, is a basic concept in mathematics. It is defined as a graph that is folded along a straight line in a plane and the parts on both sides of the straight line can completely overlap.

Axisymmetric graphics have the following characteristics:

1. Symmetry axis is unique. If a graph has multiple symmetry axes, then these symmetry axes will intersect at one point.

2. The distance from the symmetrical point of an axisymmetric figure to the axis of symmetry is equal.

3. Symmetric line segments of an axisymmetric figure are parallel to each other or on the same straight line.

Axisymmetric graphics can be seen everywhere in life, such as circles, squares, equilateral triangles, rectangles and so on.
