There, he stated: On the boundary of every convex body, there exists a point P such that every circle with center P intersects that boundary in at most 2 points. (Note that […]
Consider a set of distinct points in the plane, no three of them on the same line. Draw straight-line segments joining pairs of those points. This is called a geometric graph and here we are going to focus on the segments of such a graph. Every segment has two sides, defined by the line in […]
