Question B. Exercise caution when handling the simulation questions. C. Give you three points on a positive polygon and determine the minimum area of the polygon. Since this polygon has a maximum of 100 edges, you can calculate whether the number of edges of the polygon can be satisfied. Determine whether the conditions are met: Each angle of a triangle composed of three points is an integer multiple of the circumference angle. The precision should not be too big when determini
