The document lists and defines common 3D geometric shapes including: tetrahedron, cube, octahedron, dodecahedron, icosahedron. It also outlines different types of geometric faces such as: triangular, quadrangular, pentagonal, hexagonal. Finally, it discusses relationships between shapes like: a tetrahedron is congruent to itself, a cube and octahedron are congruent, and a dodecahedron and icosahedron are congruent.
