WebThe root will always be an internal node if the tree is containing more than 1 node. For this case, we can use the Handshake lemma to prove the above formula. A tree can be expressed as an undirected acyclic graph. Number of nodes in a tree: one can calculate the total number of edges, i.e., In graph theory, a branch of mathematics, the handshaking lemma is the statement that, in every finite undirected graph, the number of vertices that touch an odd number of edges is even. For example, if there is a party of people who shake hands, the number of people who shake an odd number of other people's hands is even. The handshaking lemma is a consequence of the degree sum …
