Let K be a convex body. In the theory of polytopal approximation, one considers the polytope Pn with n vertices, or the polytope P (n) with n facets closest to K, and the main task is to determine the asymptotic behavior of the distance of P n(or P(n)) and K. The topology on the space of convex bodies is always the same but the actual metric used depends on the nature of the problem. In this paper, we consider the most commonly used notions of distance of two convex bodies C and M. The support function of C is defined as hC (u)= max x# C (u, x).
