A tetrahedron is a three-dimensional shape that contains four vertices, four faces and six edges. This Platonic solid is classified as a polyhedron, specifically a regular convex polyhedron. This indicates that all the f... More »

Vertices are the points, or corners, in geometrical and mathematical shapes where two or more lines meet but do not cross, according to Math Open Reference. Vertices can exist in two-dimensional and three-dimensional sha... More »

A square pyramid has five vertices and five faces. The five vertices occur at each of the corners of the square base, and the final vertex is at the apex of the pyramid. The five faces are each side of the pyramid and th... More »

A tetrahedron is a shape made out of four triangular faces, and it has a total of six edges. Although each of the four sides of a tetrahedron has three edges, the shape does not have 12 edges, as some of the edges are sh... More »

A vertex is a corner on a polygon, polytope or polyhedron, and when faces, facets or edges of an object come together, a vertex forms; however, because a sphere features no meeting points, it has no vertices. Even though... More »

The number of edges of any polyhedron can be calculated using the formula: E = V + F - 2, where "E'" denotes the number of edges, "V" indicates the number of vertices and "F" represents the number of faces. It is derived... More »
