Note that B L has both triangular and quadrilateral faces. Pick integral Webtheorem [1] states that convex polyhedra are uniquely determined (up to a rigid motion) by the intrinsic geometry of their surfaces. This means that all polyhedra with surfaces isometric to S are either congruent to C or necessarily non-convex. Before we present the proof of the theorem, let us say a few words about the history of the problem. flannel knit cap ffxiv

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).
