WebJul 7, 2024 · 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. Two different graphs with 5 vertices all of degree 4. Two different graphs with 5 vertices all of degree 3. Answer.

WebBut that might not be the case. It could be a matter of drawing a new edge between two existing vertices already in the graph, for example. The relationship between the set of vertices for the "smaller" graph and the set of vertices for the "larger" graph is unclear in your exposition. But (and this is the important thing) it doesn't matter. WebWith the help of Handshaking theorem, we have the following things: Sum of degree of all Vertices = 2 * Number of edges.
