WebLemma 1 (The Handshaking Lemma): In any graph , the sum of the degrees in the degree sequence of is equal to one half the number of edges in the graph, that is . Proof: In any graph, each edge in is attached to two vertices. Therefore each edge contributes to each of the two vertices it is connected to. Therefore . For example, let's look at ...
