12. Graph Theory

Determine which graph fits the criteria: exactly five vertices and four odd vertices.

Graph $G$ is composed of vertices $H,I,J,K,L$, and edges $HI,HJ,HK,IK,JK,JL,KL$.

Which vertices are adjacent to vertex $J$?

Label the degree and parity (even/odd) of each vertex on each graph.

Label the degree and parity (even/odd) of each vertex on each graph.

Find the degree of vertex $K$.
