Pearls In Graph Theory Solution Manual

Proof by induction on n. Base case n=1: a single vertex has 0 edges, and 0 ≥ 1-1 holds. Inductive step: Assume true for all graphs with k vertices. Consider a connected graph G with k+1 vertices. Remove a vertex v of degree 1 (such a leaf exists in any finite connected graph unless it is a cycle; handle cycles separately). The remaining graph G' has k vertices and is still connected. By inductive hypothesis, G' has at least k-1 edges. Adding back v and its one edge gives at least k edges = (k+1)-1. QED.
