WebThe face on the left hand side of this arc is the outer face. If the edges aren't embedded as straight lines, then you need some extra information about the embedding, because in any plane graph you could just take an edge of the outer face and lift it around the whole embedding: this changes the outer face but doesn't move the vertexes ... WebIn this lecture we prove Euler’s theorem, which gives a relation between the number of edges, vertices and faces of a graph. We begin by counting the number of vertices, edges, and faces of some graphs on surfaces – the tetrahedron (or triangular pyramid) has 4 vertices, 6 edges, and 4 faces; the cube has 6 vertices, 12 edges, and 8 faces, etc.
