"WebSuppose that we have a graph with e edges, v nodes, and f faces. We know that the Handshaking theorem holds, i.e. the sum of node degrees is 2e. For planar graphs, we also have a Handshaking theorem for faces: the sum of the face degrees is 2e. To see this, notice that a typical edge forms part of the boundary of two faces, one to each side of it. " - Euler theorem involving sides edges and faces
