WebbThe following theorem is often referred to as the First Theorem of Graph The-ory. Theorem 1.1. In a graph G, the sum of the degrees of the vertices is equal to twice the number of edges. Consequently, the number of vertices with odd degree is even. Proof. Let S = P v∈V deg( v). Notice that in counting S, we count each edge exactly twice.
