WebAug 14, 2024 · A graph is a collection of nodes or vertices connected to each other through a collection of edges. Graphs come in two flavours, directed or undirected , each of them with their own application. Graphs with multiple edges (sometimes multiple type of edges) between the same pair of vertices are called multigraphs . Web(a) Let G be a connected, plane graph (which, in this case, can have loops and multiple edges), with n vertices, m edges and f faces. Prove Euler's Formula, n + f − m = 2 (b) Now suppose that G is simple, that every vertex has degree p ≥ 3 and every face is bounded by a cycle with exactly q ≥ 3 edges.
