The document discusses different types of 3D shapes including: - Five regular polyhedrons: tetrahedron, cube, octahedron, dodecahedron, icosahedron. - Prisms with triangular, quadrangular, pentagonal, and hexagonal sides. - Pyramids with triangular, quadrangular, pentagonal, and hexagonal bases. - Spherical solids: cylinder, cone, sphere. - Dual polyhedra pairs: tetrahedron with itself, cube with octahedron, dodecahedron with icosahedron.
