WebPolyhedra¶ A convex combination of two points is the line segment that has the two points as its ends. Given a set of points, the convex hull of the point is the set of all convex combinations of the points. For points in the plane, this convex hull is a polygon. We can draw a polygon by giving the vertices (or corner points). WebTheorem 11.1 A convex polyhedron with n vertices has at most 3n 6 edges and at most 2n 4 facets.
