WebMultiple sides and edges can intersect at one point in a 3D figure. Each such point of intersection forms a vertex. Some 3D shapes include cubes, cuboids, pyramids, spheres, and cylinders. The above figures are a cube and an octahedron. A cube has eight vertices, while an octahedron has six vertices. In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners.
