A Platonic solid is a convex regular polyhedron all the faces of which share the same regular polygon and having the same number of faces meeting at all its vertices.
You can also see some Images of Polyhedra if you want. Welcome to The Nets of the Platonic Solids Math Worksheet from the Geometry Worksheets Page at Math-Drills.com. In two dimensions there are an infinite number of regular polygons.
There are carved stones (dated approximately 2000 BC) that have been discovered in Scotland. Compare with the Kepler solids, which are not convex, and the Archimedean and Johnson solids, which while made of regular polygons are not themselves regular.. The Cube is the most famous one, of course, although he likes to be called “hexahedron” among friends.
Some of them are carved with lines corresponding to the edges of regular polyhedra. They appear in crystals, in the skeletons of microscopic sea animals, in children’s toys, and in art. See also platonic solids in 4D. I.e.

The Platonic Solids are the five regular convex polyhedra. In three dimensions there are just five regular polyhedra. Also the other platonic solids are named after the number of faces (or hedra) they have. It may be printed, downloaded or saved and used in your classroom, home school, or other educational environment to help someone learn math. Platonic solids were known to humans much earlier than the time of Plato. (Now you know how to count in classical Greek, too!) The names of the platonic solids reflect the number of faces that each one possesses. They have been studied by many philosophers and scientists such as Plato, Euclid, and Kepler. The Platonic solids, or regular polyhedra, permeate many aspects of our world.
The term platonic is derived from the name of the Greek philosopher Plato, who is believed to have lived from around 423 to 347 BCE.Plato is known to have written about the shapes we know today as the platonic solids, although not in a particularly mathematical context. A platonic solid (also called regular polyhedra) is a convex polyhedron whose vertices and faces are all of the same type. Tetrahedron, Octahedron, Dodecahedron, Icosahedron. Construction Tips.
