What are the polygons with an axial symmetry?


All regular polygons have at least one axial symmetry.

A regular polygon with as many axes of symmetry as it possesses sides.

The axes of symmetry pass through the center of the polygon and the center of each side or each vertex/corner.

What are the polygons with a central symmetry?


All regular polygons with an even side number have a central symmetry (the center of the polygon). Polygons with an odd number of sides have no central symmetry.
