WebDefinition − A Tree is a connected acyclic undirected graph. There is a unique path between every pair of vertices in G. A tree with N number of vertices contains ( N − 1) number of edges. The vertex which is of 0 degree is called root of the tree. The vertex which is of 1 degree is called leaf node of the tree and the degree of an internal ... WebMay 11, 2024 · Each labelled spanning tree can be formed in this way as well. Thus we have a bijection between the number of labelled spanning trees and the number of ways we can remove two edges of this graph to make the graph acyclic. So how many ways can we remove these edges? If we choose the chord at all, we have $n$ choices for the other edge.
