WebJun 15, 2024 · A polyhedron is a 3-dimensional figure that is formed by polygons that enclose a region in space. Each polygon in a polyhedron is a face. The line segment where two faces intersect is an edge. The point of intersection of two edges is a vertex. Figure 9.1. 1. Examples of polyhedrons include a cube, prism, or pyramid. WebJan 1, 2024 · By a map we mean a polyhedral map on a surface. So, a face of a map is an n-gon for some n ≥ 3 and two intersecting faces intersect either on a vertex or on an edge. A map on a surface is also called a topological tiling of the surface.
