Platonic Solids
There are five Platonic Solids.
Each one is a polyhedron (a solid with flat faces).
They are special because every face is a regular polygon of the same size and shape.
Example: each face of the cube is a square.
They are also convex (no "dents" or indentations in them).
They are named after Plato, a famous Greek philosopher and mathematician.
