WebbA vertex u is called a pendent vertex of G if d G(u) = 1. An edge uv is called a pendent edge of G if d G(u) = 1 or d G(v)=1. Let d(u,v G) denote the distance between u and v in V(G). The diameter of a graph G is the maximum distance between pairs of … Webb3. Every non-pendant vertex of a tree is a cut vertex. We now give the first result which characterises cut vertices. Theorem 5.1 IfG(V, E) isa connectedgraph, thenv isa cut vertex ifthere exist vertices u, w∈V −{v} such that every u−w path in G passes throughv. Proof Let G(V, E) be a connected graph and let v be the cut vertex of G ...
