WebShow that a connected graph on n vertices is a tree if and only if it has n − 1 edges. ( ⇒) If a tree G has only 1 vertex, it has 0 edges. Now, assume that any tree with k − 1 vertices has k − 2 edges. Let T be a tree with k vertices. Remove a leaf l to obtain a tree T ′ with k − 1 vertices. Then, T ′ has k − 2 edges, by the inductive hypothesis. WebOct 12, 2024 · A directed graph is a tree when the following three conditions are true: The graph is a connected graph.

WebIn computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes. Each node in the tree can be connected to many children (depending on the type of tree), but must be connected to exactly one parent, except for the root node, which has no parent. WebApr 2, 2014 · 1 If the assumption that a proposition is false leads to a contradiction, then the assumption is incorrect and the proposition must be true. In the proof that every subgraph of a tree is a tree we are given that the graph is connected since it is a tree and trees are connected by definition.
