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
Circle Line Sightseeing Cruises Circle Line took delivery of the third of three new vessels constructed by Gladding-Hearn Shipbuilding in Somerset, Massachusetts. In January 2017, Circle Line Sightseeing Cruises purchased New York Water Taxi—among the assets acquired was the latter company's Circle Line Downtown brand, reuniting both Circle Lines under one owner. Circle Line was awarded with proclamations by two New York City mayors. In 1985, then Mayor Ed Koch proclaimed April 23 "Circle Line Day." Approximately 20 years later current Mayor Mike Bloomberg proclaimed September 17 "Circle Line Sightseeing Cruises Day" in 2008. In 2001, Circle Line vessels helped transport victims of the
