Expert Solution
Step 1

Two graphs are equivalent if they both have the same number of edges and vertices. Moreover, if any vertex is connected to another vertex in one graph, the same should be the case in the second graph.

Given that there are two graphs.

The first graph has 6 vertices, namely, A,B,C,D,E,F and the second graph also has 6 vertices, namely, A,B,C,D,E,F.

So, the vertices are the same in both graphs.

 

The edges in the first graph are AD, AE, BD, BF, CF, CE.

The edges in the second graph are AE, EF, FC, CB, BD, DA.
