Written beneath each shape is their name; tetrahedron, cube, octahedron, dodecahedron and icosahedron., A 3D shape with regular polygonal faces, meeting at equal angles, is a platonic solid.

Mathematicians have spent more than 2,000 years dissecting the structure of the five Platonic solids—the tetrahedron, cube, octahedron, icosahedron, and dodecahedron—but there’s still a lot ...

A polygon is regular if it is uniform and its faces are all alike. The regular convex polyhedra are the five Platonic solids, which have been known since classical Greece. The ancient Greek ...

THERE are five Platonic solids of perfect symmetry. Three, the tetrahedron, octahedron and icosahedron, have triangular faces. A fourth, the cube, has square faces. The fifth, the dodecahedron ...
