There are different numbers on the different platonic solids.
Symmetry. Perfect symmetry. Equality of angles, edges and vortices.
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.
It is an octahedron which is one of the Platonic Solids having 8 equilateral triangular faces and 12 edges.
The Platonic solids were name after the Greek philosopher Plato, who theorized that the classical elements were constructed from the regular solids.
Euclid was the one who proved that there are only five platonic solids.
There (not their) are 5 platonic solids.
Symmetry. Perfect symmetry. Equality of angles, edges and vortices.
A rectangular prism (cuboid) and a hexagon-based pyramid, for example, both have 12 edges. Of the five Platonic solids, an octahedron and a cube each have 12 edges.
Because 6 platonic solids would be too many, and 4 wouldn't be enough
Because 6 platonic solids would be too many, and 4 wouldn't be enough
A cube has 12 edges as does an octahedron and those are the two platonic solids (convex polyhedra with congruent regular polygons as faces where the same number of faces meet at each vertice) with 12 edges.
The book called Platonic Solids: The experience
An icosahedron has 20 triangular faces, 30 edges and 12 vertices. Its main geometric significances is that it is has five platonic solids.
