Answer
no. of vertices= 9
no. of edges= 12
degree of vertex a = 3
degree of vertex b = 2
degree of vertex c = 4
degree of vertex d = 0
degree of vertex e = 6
degree of vertex g = 4
degree of vertex h = 2
degree of vertex i = 3
degree of vertex f = 0
there is no pendent vertex
vertex d and f are isolated vertex
Work Step by Step
no of vertices in graph are 9
no of edges which connect one graph to another are 12
The degree of a vertex represents the number of edges incident to that vertex.
degree of every vertices is written as degree of a is 3 and b is 2 and c is 4 so on.
as no vertex has one degree so there is no pendent vertex
2 vertex d and f has zero degree so there is two isolated vertex
