Question
This question concerns subgraphs of graphs. In all cases, when we say \( G_1 \) is a subgraph of \( G_2 \), we mean that \( G_1 \) is isomorphic to some subgraph of \( G_2 \). Are the following statements true or false? 1. \( C_3 \) is isomorphic to \( K_3 \). 2. If a graph contains no cycles, then none of its subgraphs contain cycles. 3. \( C_4 \) is a subgraph of \( K_{2,2} \). 4. Every bipartite graph is isomorphic to \( K_{m,n} \) for some values of \( m \) and \( n \). 5. \( P_3 \) is a subgraph of \( K_{2,2} \). 6. \( C_4 \) is a subgraph of \( P_4 \).
