An identical number of faces meet at each vertex. There are just 5 Platonic solids: tetrahedra, hexahedra, octahedra, dodecahedra and icosahedra. The oldest man-made Platonic solids are over 4000 years old. The Platonic solids are the five convex regular polyhedra. Each one has identical regular faces, and identical regular vertex figures.

Three of the regular polyhedra, or Platonic solids, can also be stellated. The edges of the cube and tetrahedron once extended never meet, thus they have no stellations.
