Video: Gumdrop Platonic Solids The five Platonic solids are the tetrahedron, the cube, the octahedron, the dodecahedron, and the icosahedron. Their faces are regular polygons. These solids are perfectly symmetrical in that each face of a solid is identical to every other face of the solid, each vertex is identical to every other vertex, and each edge is identical to every other edge. Each Platonic solid has a dual: a solid whose vertices correspond to the faces, and faces to the vertics. The dual of the cube is the octahedron. The dual of the dodecahedron is the icosahedron. The tetrahedron is its own dual.
