Graph is tree or not

WebIn the mathematical field of graph theory, a spanning tree T of an undirected graph G is a subgraph that is a tree which includes all of the vertices of G. [1] In general, a graph may have several spanning trees, but a graph that is not connected will not contain a spanning tree (see about spanning forests below). WebOkay, So recall that a tree is a connected undirected graph with no simple circuits. So a tree a tree is a connected laughing card is a connected, undirected graph green undirected graph with no simple circuits. So Okay. Okay. So for a um yes, right? Yes. We have a connected undirected graph here with no simple circuit. So yes, a is a tree, so ...

Graph and its representations - GeeksforGeeks

In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees.
