Web4 Graph Theory III Definition. A tree T = (V,E) is a spanning tree for a graph G = (V0,E0) if V = V0 and E ⊆ E0. The following figure shows a spanning tree T inside of a graph G. = T Spanning trees are interesting because they connect all the nodes of a graph using the smallest possible number of edges. WebA tree T is said to be a spanning tree of a connected graph G if T is a subgraph of G and T contains all vertices of G. For instance, the subgraph in heavy lines in Fig. 3-17 is a spanning tree of the graph shown. Fig. 3-17 a spanning tree of the graph. A spanning tree is sometimes referred to as a skeleton or scaffolding of G.

The diagram of a tree is described as follows: The above graph is an undirected graph which has only a path to connect the two vertices. So this graph is a tree.
