ICOSAHEDRON & DODECAHEDRON |

 |
 |
|
 |
The
centres of the faces of an icosahedron determine a dodecahedron… and
the centres of the faces of a dodecahedron determine an icosahedron so
that the dodecahedron and the icosahedron are dual. This means that the
two figures have the same elements of symmetry. |
|
 |
While on the subject of symmetries, how many categories can the 5 regular polyhedra be grouped into? |
