Question

verification of EULERS​

Answer 1

Answer:

Twenty Proofs of Euler's Formula: V-E+F=2. ... This page lists proofs of the Euler formula: for any convex polyhedron, the number of vertices and faces together is exactly two more than the number of edges. Symbolically V−E+F=2. For instance, a tetrahedron has four vertices, four faces, and six edges; 4-6+4=2.
