WebTheorem (Handshake lemma). For any graph X v2V d v= 2jEj (1) Theorem. In any graph, the number of vertices of odd degree is even. Proof. Consider the equation 1 modulo 2. We have degree of each vertex d v 1 if d vis odd, or 0 is d vis even. Therefore the left hand side of 1 is congruent to the number of vertices of odd degree and the RHS is 0. how do you spell arbitraryIn graph theory, a branch of mathematics, the handshaking lemma is the statement that, in every finite undirected graph, the number of vertices that touch an odd number of edges is even.
