WebA convex polyhedron is also known as platonic solids or convex polygons. The properties of this shape are: All the faces of a convex polyhedron are regular and congruent. Convex polyhedrons are 3D shapes with polygonal faces that are similar in form, height, angles, and edges. In a convex polyhedron, all the interior angles are less than 180º.

Simple though it may look, this little formula … Many of the most studied polyhedra are highly symmetrical, that is, their appearance is unchanged by some reflection or rotation of space. Each such symmetry may change the location of a given vertex, face, or edge, but the set of all vertices (likewise faces, edges) is unchanged. The collection of symmetries of a polyhedron is called its symmetry group. darling range location

In geometry, a uniform polyhedron is a polyhedron which has regular polygons as faces and is vertex-transitive (transitive on its vertices, isogonal, i.e. there is an isometry mapping any vertex onto any other).
