This document lists and defines the main 3D geometric shapes: the tetrahedron, cube, octahedron, dodecahedron, and icosahedron. It also outlines the different types of sides the shapes can have, such as triangular, quadrangular, pentagonal, and hexagonal sides. Finally, it notes relationships between the shapes, such as how a tetrahedron is made up of itself, and how a cube and octahedron and a dodecahedron and icosahedron are related.
