005 Mathart - Platonic Solids - Tetrahedron 02 - 10 cm A platonic solid is a convex polyhedron that's totally regular in its construction. It features congruent regular polygonal faces of the same shape and size with identical vertices where multiple faces intersect. Among five exceptional solids meeting these strict criteria are the tetrahedron, cube, octahedron, dodecahedron, and icosahedron. The Tetrahedron is a distinct polyhedron comprising four triangular faces, six straight edges that connect them perfectly, and four uniquely-shaped vertex corners where all angles meet.
