Graph Theory: 56. Central Vertices are in a Single Block

Recall that a block in a graph is a maximal nonseparable subgraph, and the centre of a graph is the set of all vertices whose eccentricity is equal to the radius (minimum eccentricity). In this video we walk through a proof that the centre of every connected graph lies in a single block of the graph. The proof method is by contradiction.
