Theorem 3.1.2. Let x be a edge of a connected graph G. The following statements are equivalent: (1) x is a bridge of G. (2) x is not on any cycle of G. (3) There exist vertices u and v of G such that the edge x is on every path joining u and v. (4) There exists a partition of V into subsets U and W such that for any vertices u E U and wE W the edge x is on every path joining u and w.
