WebThree or more edges enclose one of the faces of a polyhedron. The polyhedron above has triangles and pentagons for its faces. Note the triangle (in yellow) is formed by 3 edges and the pentagon (in red) is formed by 5 edges. Polyhedra and nets. A two-dimensional model for a polyhedron can be created by cutting some of the edges of its faces. WebSince each vertex of a polyhedron belongs to some face, all face- connected polyhedra are vertex-connected. But not vice versa; figure 8. isn't face-connected, because there's no path of edges and faces from the top face to the bottom face. Figures 8.4 to 8.4 and 8.4 to 8.4 are all face-connected.
