WebThe claim: If G is a graph on n nodes, where n is an even number, then if every node of G has a degree of at least n / 2 then G is connected. My proof: Assume that G is connected. Since it is connected, then by definition there exists a path between any two vertices, and there must be at least n = 2 vertices in G.
