Answer

Number of vertices = 6 Number of edges = 6 Deg(a) = 2 Deg(b) = 4 Deg(c) = 1 Deg(d) = 0 Deg(e) = 2 Deg(f) = 3 c is pendant and d is isolated.

Work Step by Step

Number of vertices = 6 Number of edges = 6 The degree of vertex in an undirected graph is the number of edges incident on it. Deg(a) = 2 Deg(b) = 4 Deg(c) = 1 Deg(d) = 0 Deg(e) = 2 Deg(f) = 3 c is pendant because it's degree is 1. d is isolated because it's degree is 0.
