Platonic solids are the five geometric solids whose faces are all identical, regular polygons meeting at the same three-dimensional angles. Also known as the five regular polyhedra, they consist of the tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron. Pythagoras probably knew the ... | 677.169 | 1 |

We know that a right triangle is a triangle having a right
angle, where the side opposite the right angle is the hypotenuse,
and the perpendicular sides are the legs of the right triangle.
The Pythagorean theorem gives the relationship between the
lengths of the sides of a right triangles.
