## Platonic Solids | ## more ... |

There are five Platonic Solids. Each one is a polyhedron (a solid with flat faces) They are special because every face is a regular polygon of the same size and shape. Example: each face of the cube is a square. They are also convex (no "dents" or indentations in them). They are named after Plato, a famous Greek philosopher and mathematician. See: Regular Polygon |
