Thread: isomorphic or not

Hello,
plz try to solve this question

To be isomorphic , two graphs must have the same number of vertices and the same number of edges.

Have you compared the degree sequences of the two graphs?

Point B has degree 4.
While no such point exists in the second graph.
Conclusion is that they are not isomorphic.

Hello,
As both the graph have the same number of verticles. but graph G has 7 edges and graph G, has only 6 edges.therefore the two graphs are not isomorphic.
