Euler's graph theory
WebEuler's formula applies to polyhedra too: if you count the number of vertices (corners), the number of edges, and the number of faces, you'll find that . For example, a cube has 8 vertices, edges and faces, and sure enough, . Try it out with some other polyhedra yourself. Why does this same formula work in two seemingly different contexts? WebEulerization is the process of adding edges to a graph to create an Euler circuit on a graph. To eulerize a graph, edges are duplicated to connect pairs of vertices with odd degree. …
