Dividing a circle into areas "F" can also be derived, which will solve the problem. Its vertices include the "n" points on the circle, referred to as the exterior vertices, as well as the interior vertices, the intersections of distinct chords in the interior of the circle. The "generic intersection" assumption made above guarantees that each interior vertex is the intersection of no more than two chords. Thus the main task in determining "V" is finding the number of interior vertices. As a consequence of the lemma, any two intersecting chords will uniquely determine an interior vertex. These chords are in turn uniquely determined by
Into a Circle March 1988, and reached No. 5 in the chart. Into a Circle embarked on their final tour in September 1989, with Annie Anxiety joining the line-up on backing vocals. The band broke up in October 1989. Hampshire is a member of Thailand-based band Futon, alongside Simon Gilbert (Suede).
