"WebPolyhedrons. A polyhedron is a 3-dimensional figure that is formed by polygons that enclose a region in space. Each polygon in a polyhedron is called a face. The line segment where two faces intersect is called an edge and the point of intersection of two edges is a vertex. There are no gaps between the edges or vertices in a polyhedron.
