> If P is the set of all points on the circle, then the set of all cords is the set of all possibilities of (p1, p2), where p1 and p2 are in P. So you are in favour of method 2. But method 3 says: Take a random point inside the circle, and use this as a center point of the cord. What do you find wrong with this method?
