Best Answer

V= number of vertices

E= number of edges

F= number of faces

For ALL convex polyhedra V-E+F=2

(Euler Characteristic of closed convex polyhera is 2; the genus is 2-2=1)

For a torus (donut shape) V-E+F = 3 (genus is 3-2= 1)

A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices.

A triangular pyramid is one with a triangle shaped base and triangular sides (4 sides, all of them identical), therefore it would only have 6 edges and 4 vertices There are eight edges in a triangular pyramid, and there are five vertices on a triangular pyramid. Edges are the places where two flat surfaces meet. Vertices are the places where three or more flat surfaces meet. * * * * * The sides of a triangular pyramid need not be identical.
