2C Using the Sum of Degrees Theorem in Graph Theory to Find the Number of Edges or Sum of Degrees
In Graph Theory, the Sum of the Degrees Theorem says that the sum of the degrees of the vertices in a graph will equal twice the number of edges. (This was explained in more detail in the previous video. "Counting Edges and Underzstanding teh Sum of Degrees Theorem in Graph Theory" at • 2B Counting Edges and Understanding the Su... . In this video, we will use the theorem to solve 3 problems.
