WebSep 12, 2024 · Graph1 is not a tree since it has a cycle, but the graph2 is a tree since it's acyclic. Moreover, it's a binary tree also which is not necessarily to be. So to check … WebA connected acyclic graph is called a tree. In other words, a connected graph with no cycles is called a tree. The edges of a tree are known as branches. Elements of trees are called their nodes. The nodes without child nodes are called leaf nodes. A tree with ‘n’ vertices has ‘n-1’ edges.
