A platonic solid is a convex Polyhedron that satisfy these three characteristics:

  • Made up of regular polygons.
  • All faces are congruent.
  • All corners are congruent. 
  • The same number of faces meet at every vertex.

3 Platonic solids are made of equilateral triangles
tetrahedron, octahedron, icosahedron

One platonic solid is made of squares, a cube.

One platonic solid is made of pentagons, a dodecahedron.

Here are the 5 platonic solids and their characteristics.

  • 3 squares at each corner.
  • 6 square faces.

Tetrahedron

  • 3 equilateral triangles at each corner.
  • 4 triangle faces.

Octahedron
