Suppose there are $n$ points equally spaced ( i.e. the distances between two consecutive points are same) on the circumference of a circle. Now if we join each point with every other points by a straight line then how many points of intersection will be there ?

I tried to find a recurrance relation. Is there a recurrance relation to solve for the number of points of intersection ?
