http://personal.kent.edu/%7Ermuhamma/GraphTheory/MyGraphTheory/planarity.htm WebFor Graph Theory Theorem (Euler’s Formula) If a ﬁnite, connected, planar graph is drawn in the plane without any edge intersections, and v is the number of vertices, e is the number of edges and f is the number of faces (regions bounded by edges, including the outer, inﬁnitely large region), then v +f e = 2: WebEulers First Theorem The statement (a) If a graph has any vertices of odd degree, then it cannot have an Euler circuit. (b) If a graph is connected and every vertex has even degree, then it has at least one Euler circuit. Using the theorem We need to check the degree of the vertices.
