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
Fife Circle Line Fife Circle Line The Fife Circle is the local rail service north from Edinburgh. It links towns of south Fife and the coastal towns along the Firth of Forth before heading to Edinburgh. Operationally, the service is not strictly a circle route, but, rather, a point to point service that reverses at the Edinburgh end, and has a large bi-directional balloon loop at the Fife end. The service includes the Edinburgh-Dunfermline stretch of the East Coast Main Line, which includes the world-famous Forth Bridge. On the Fife side, while this line hugs the coast, the circle is formed by a
