There are only five solids that can be called platonic solids – the tetrahedron, the hexahedron or cube, the octahedron, the dodecahedron and the icosahedron. They are also called regular geometric solids or polyhedra and are 3D in shape. Each face of a Platonic Solid is the same regular sized polygon. The name of each shape is derived from the number of its faces – 4 (tetrahedron), 6

The term platonic solids refers to regular polyhedra. In geometry, a polyhedron, (the word is a Greek neologism meaning many seats) is a solid bounded by plane surfaces, which are called the faces; the intersection of three or more edges is called a vertex (plural: vertices).

There are only five solids that can be called platonic solids – the tetrahedron, the hexahedron or cube, the octahedron, the dodecahedron and the icosahedron. They are also called regular geometric solids or polyhedra and are 3D in shape. Each face of a Platonic Solid is the same regular sized polygon. The name of each shape is derived from the number of its faces – 4 (tetrahedron), 6 Platonic Solids (Regular polytopes in 3D) Written by Paul Bourke December 1993.

A regular polyhedron is a convex object in 3- dimensional space made up of a collection of regular n-gons Notice that as n gets larger, the regular polygon looks more and more like a circle . In 3-D, the text comments that "the sphere is the most symmetrical of solids in Platonic Solids. The platonic solids (or regular polyhedra) are convex with faces composed of congruent , convex regular polygons . The mathematician Euclid 7 Jul 2007 Platonic Solids 2. A regular tetrahedron and a regular octahedron are two of the five known Platonic.

Add a corner more and you get a square, add another corner more and you get a pentagon.

Platonic solidsare completely regular solids whose faces are equiangular and equilateral polygons of equal size. An identical number of faces meet at each vertex. There are just 5 Platonic solids: tetrahedra, hexahedra, octahedra, dodecahedra and icosahedra. The oldest man-made Platonic solids are over 4000 years old.

The oldest man-made Platonic solids are over 4000 years old. The Platonic solids are the five convex regular polyhedra.

The Socratic tradition was not particularly congenial to mathematics, as may be gathered from Socrates' inability to convince himself that 1 plus 1 equals 2, but it seems that his student Plato gained an appreciation for mathematics after a series of conve The regular star polyhedra can also be obtained by facetting the Platonic solids.

philisopher Plato. There are just five of them: tetrahedron - 4 triangles. cube (or hexahedron) - 6 squares. octahedron - 8 triangles. dodecahedron - 12 pentagons.

The most basic regular polygon is a regular triangle. Add a corner more and you get a square, add another corner more and you get a pentagon. Platonic solids, as ideas and concepts, have been with us ever since Plato decided to tell an origin story of the universe. Plato's universe originated with a master craftsman, a demiurge, that created the essential elements that make up reality, ourselves included: "[T]he Craftsman begins by fashioning each of the four kinds “to be as… Five Platonic Solids: Tetrahedron, Octahedron, Hexahedron (Cube), Icosahedron, Dodecahedron.

They are named after the ancient Greek philosopher Plato who theorized that the classical elements were constructed from the regular solids.
