The five Platonic solids are the foundation for a number of geometric studies, and they encompass the only three-dimensional polyhedrons that are both regular and convex. In other words, they are ...

Pierre-Philippe Dechant. Platonic solids generate their four-dimensional analogues. Acta Crystallographica Section A Foundations of Crystallography, 2013; 69 (6): 592 DOI: 10.1107/S0108767313021442 ...

And shapes with more sides, like heptagons or octagons, can’t fit together to make the minimum three faces to make a corner. Therefore we can only make five Platonic solids.

Plato turned that into the Platonic solids, which are a series of regular 3D shapes, meaning with sides that are all squares, for example, or equilateral triangles —the 3D versions of different ...

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 ...
