Platonic solids are three-dimensional shapes that have equal sides, angles, and faces. There are five Platonic solids.
* The tetrahedron is a four-sided polyhedron with four equilateral triangles for faces. It looks like a three-sided pyramid (where the fourth side is the base). * The cube is a six-sided polyhedron with six squares for faces. * The octahedron is an eight-sided polyhedron with eight equilateral triangles for faces. It looks like two four-sided pyramids attached at their bases. * The dodecahedron is a 12-sided polyhedron with twelve equilateral pentagons for faces. * The icosahedron is a 20-sided polyhedron with twenty equilateral triangles for faces. There are illustrations of them at the websites listed in the links section.
I think you probably mean platonic. The cube is one of only five platonic solids. These are the only shapes that can be made with outward-pointing corners and sides all of the same lengths.
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
false
triangles, squares and pentagons.
The corresponding sides of similar solids have a constant ratio.
There (not their) are 5 platonic solids.
The book called Platonic Solids: The experience
There are different numbers on the different platonic solids.
We don't know for certain who discovered the platonic solids first. However, Pythagoras is credited by some sources as discovering the platonic solids first. Other sources credit Theaetetus as being the first to describe all five platonic solids and proving that these are the *only* platonic solids.
