The six spheres each corresponded to one of the planets (Mercury, Venus, Earth, Mars, Jupiter, and … See more In geometry, a Platonic solid is a convex, regular polyhedron in three-dimensional Euclidean space. Being a regular polyhedron means that the faces are congruent (identical in shape and size) regular polygons See more A convex polyhedron is a Platonic solid if and only if 1. all its faces are congruent convex regular polygons, 2. none of its faces intersect except at their … See more Angles There are a number of angles associated with each Platonic solid. The dihedral angle is the interior angle between any two face planes. The dihedral angle, θ, of the solid {p,q} is given by the formula See more The tetrahedron, cube, and octahedron all occur naturally in crystal structures. These by no means exhaust the numbers of possible forms of crystals. However, neither the regular … See more The Platonic solids have been known since antiquity. It has been suggested that certain carved stone balls created by the late Neolithic people of Scotland represent these shapes; … See more The classical result is that only five convex regular polyhedra exist. Two common arguments below demonstrate no more than five Platonic solids can exist, but positively demonstrating the existence of any given solid is a separate question—one that … See more Dual polyhedra Every polyhedron has a dual (or "polar") polyhedron with faces and vertices interchanged.
