Definition3.6 The convex hull of a finite point set PˆRd forms a convex polytope. Each p2Pfor which p=2conv(Pn fpg) is called a vertex of conv(P). A vertex of conv(P) is also called an extremal point of P. A convex polytope in R2 is called a convexpolygon. builders warehouse botswana contact number
