There are 5 "Platonic solids" that were identified by the Greek mathematician Plato. They are three dimensional solids (polyhedra) having the following properties:

- The faces of the shape are regular polygons. That is, they have all sides and interior angles equal.
- All the faces are congruent. That is they are all identical in shape and size.

Tetrahedron | 4 faces | |

Cube (Hexahedron) |
6 faces | |

Octahedron | 8 faces | |

Dodecahedron | 12 faces | |

Icosahedron | 20 faces |
