Archimedean solids are related to the five Platonic Solids. Remember that the Platonic solids are the only regular, convex solids. What happens if we loosen the constraint of regularity?
Instead of requiring that the faces meeting at a vertex be the same polygon, we now require that
Truncation means cutting off the
corners of a solid. We cut off identical lengths along each edge
emerging from a vertex. This process adds a new face to the
polyhedron. Each of the following pages explains the process in more
detail.
Truncated Tetrahedron
Truncated Cube
Truncated Octahedron
Truncated Icosahedron
Truncated Dodecahedron
Cuboctahedron
Icosidodecahedron
If we truncate the cuboctahedron or the icosidodecahedron, we will
obtain four more solids.
Rhombitruncated
Cuboctahedron
Rhombicuboctahedron
Rhombitruncated
Icosidodecahedron
Rhombicosidodecahedron
