In this way he made all five three-dimensional polytopes (the tetrahedron, cube, octahedron, dodecahedron and icosahedron). Then he started on the four-dimensional polytopes.

The ancient Greek mathematician Euclid proved in his Elements of Geometry that there are only five Platonic solids – the regular tetrahedron (four sides that are equilateral triangles), the cube (six ...

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 ...
