Every polygon has the same number of sides as it has vertices. For example a triangle will have 3 sides and 3 vertices and a cube will have 4 sides and 4 vertices.

If all the sides and all the angles of a polygon are equal the polygon is said to be regular.

Square: All sides and all angles are equal in measure.

A regular polygon is equilateral and equiangular as is the quadrilateral shown here.

Shown here are the first eight regular polygons. Note that the angles and sides of each polygon are of equal measure.
