Determine which among the four graphs pictured in Figure 2 are isomorphic. For each pair of isomorphic graphs, describe an isomorphism between them. For each pair of graphs that are not isomorphic, give a property that is preserved under isomorphism such that one graph has the property, but the other does not. For at least one of the properties you choose, prove that it is indeed preserved under isomorphism (you only need prove one of them). 00 4 10 7 (a) Gi 3 10 8 (c) G3 3 10 Figure 2 (b) G2 10 6 (d) Ga 2 Determine which among the four graphs pictured in Figure 2 are isomorphic.
