Polyhedron wikipedia
WebRegular Polyhedrons. A polyhedron is said to be regular if its faces are made up of regular polygons and the same number of faces meet at each vertex. 1. This polyhedron is regular. 2. Its faces are congruent, regular polygons. Vertices are formed by the same number of faces. 1. This polyhedron is not regular.
