Consider the following four graphs G 1. Oz. 03. and G4: (I) G I (b) 62 Figure 'l. 4 potentially isomorphic graphs. I. Determine which among the four graphs pictured in Figure l are isomorphic. :- For each pair of isomorphic graphs. describe an isomorphism between them. I 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. 2. For at least one of the properties you used above to show that two graphs are not isomorphic. prove that the property is indeed preserved under isomorphism
