The regular polyhedra are five

add to album

A way to see why there are only 5 regular polyhedra: we can use pentagons as faces of a polyhedron only if we put 3 pentagons around each vertex (so we get the dodecahedron).
The image has been realized for the exhibition Simmetria, giochi di specchi - Symmetry, playing with mirrors.

The image belongs to the sections...:
