Q5 graph theory

WebThe graph is a mathematical and pictorial representation of a set of vertices and edges. It consists of the non-empty set where edges are connected with the nodes or vertices. The nodes can be described as the vertices that correspond to objects. The edges can be referred to as the connections between objects. WebApr 15, 2024 · For each of the following, try to give two different unlabeled graphs with the given properties, or explain why doing so is impossible. Two different trees with the same number of vertices and the same number of edges. A tree is a connected graph with no cycles. Two different graphs with 8 vertices all of degree 2.
