Determine if the graphs below are isomorphic. Explain your answer.

Solution

(1) for graph to be isomorphic it should have same number of vertices and edges .

so as seen above both graph have same number of vertices and edges

(2) degree of each vertex should be same - in above case it is not verified . in first graph degree of vertex is less than that of second graph

therefore these are not isomorphic.
