The 5 regular polyhedra

A regular polyhedron is a solid bounded by identical faces which are regular polygons. It is possibile to build only 5 regular polyhedra: the cube (6 squared faces), the tetrahedron (4 triangular faces), the octahedron (8 triangular faces), the dodecahedron (12 pentagonal faces) and the icosahedron (20 triangular faces).

A regular polyhedron is included into another if the centers are the same and all the vertices of the first polyhedron lie on the surface of the second one.
