Polyhedrons {regular polyhedron} {regular solid} {Platonic solid} can have same regular polygon for all faces: four equilateral triangles {regular tetrahedron}, six squares {cube, Platonic solid}, six regular hexagons {regular hexahedron}, eight equilateral triangles {regular octahedron}, twelve regular pentagons {regular dodecahedron}, and twenty equilateral triangles {regular icosahedron}. All vertices are on circumscribed sphere. Concave regular polyhedrons are small stellated dodecahedron, great dodecahedron, or great icosahedron.
