In Euclidean geometry, a Platonic solid is a regular, convex polyhedron wi congruent faces o regular polygons an the same nummer o faces meetin at each vertex. Five solids meet those criteria, an each is named efter its nummer o faces.
|Cube or hexahedron
Geometers have studied the mathematical beauty an symmetry o the Platonic solids for thoosands o years. Thay are named for the auncient Greek filosopher Plato who theorized in his dialogue, the Timaeus, that the classical elements wur made o these regular solids.
