A polygon is a two-dimensional shape bounded by straight-line segments. A polygon is said to be regular if the edges are of equal length and meet at equal angles. A polygon is convex if the line connecting any two points inside the polygon is itself entirely inside the polygon.

Since all faces are identical, regular polygons and the vertices are identical, stating the number of sides of a face and the number of faces that meet at each vertex fully specifies one of these solids.
