"In graph theory, the degree (or valency) of a vertex of a graph is the number of edges that are incident to the vertex; in a multigraph, a loop contributes 2 to a vertex's degree, for the two ends of the edge. The degree of a vertex $${\displaystyle v}$$ is denoted $${\displaystyle \deg(v)}$$ See more The degree sum formula states that, given a graph $${\displaystyle G=(V,E)}$$, $${\displaystyle \sum _{v\in V}\deg(v)=2 E \,}$$. The formula implies that in any undirected graph, the number … See more • A vertex with degree 0 is called an isolated vertex. • A vertex with degree 1 is called a leaf vertex or end vertex or a pendant vertex, and the edge incident with that vertex is called a pendant edge.
