Theorem:
Let G be a simple graph on n >= 3 vertices such that deg_G(v) >= n/2 for every vertex v in V(G). Then deleting any vertex of G results in a connected graph.

Proof:
Let G be a simple connected graph on n >= 3 vertices, and suppose G has a vertex v such that removing v from G results in a disconnected graph (namely, G - {v} -- ...
