online.math.uh.edu1. A polyhedron is composed entirely of polygons; each of these polygons is known as a face. 2. The segment where two polygons intersect is known as an edge, and the edge is a shared side of the two polygons. 3. The point where three or more edges intersect is known as a vertex. The vertices of the polyhedron are the vertices of the polygons.
