Thus, the sum of the angles of any polygon is: S = ( n – 2) * 180. For example, the sum of all eight angles of an octagon is: S = (8 – 2) * 180 = …
WebLet S be a set of n points in the general position, that is, no three points in S are collinear. A simple k-gon with all corners in S such that its interior avoids any point of S is called a k-hole. In this paper, we present the first algorithm that counts the number of non-convex 5-holes in S. To our best knowledge, prior to this work there was no known algorithm in the …
