State and prove the handshaking theorem
In 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. For example, if there is a party of people who shake hands, the number of people who shake an odd number of other people's hands is even. The handshaking lemma is a consequence of the degr… Web1 Answer. In electrostatics, Gauss’ Law connects the electric flux going through a closed path with the charge contained within it. This formula is extremely useful for calculating the electric field produced by various charged substances of varied forms. By tracing a closed Gaussian surface across a point outside an equally thin charged ...

WebFeb 9, 2024 · Theorem 2. A simple finite undirected graph has an even number of vertices of odd degree. Proof. By the handshake lemma , the sum of the degrees of all vertices of odd degree must be even, which is only possible if their number is even. . The following two statements about trees also follow from the handshake lemma.
