Any connected graph with n vertices and n−1 edges is a tree For a tree (T), there is one and only one path between every pair of vertices in a tree. A tree is a connected graph containing no cycles nocturnal123 answered Aug 21, 2020 nocturnal123 comment Share Follow See all 0 reply Please log in or register to add a comment.
