Originally called the “Chenango Triangle,” the Town of Triangle derives its name from its geographical location – the confluence of the Tioughnioga and Otselic Rivers form the angle of the “Triangle.”  The Towns of Triangle, Barker, and Nanticoke were originally part of the Town of Lisle.  On April 18, 1831, the three towns were separated from the Town of Lisle.  The Town of Triangle includes the Village of Whitney Point, the Hamlet of Triangle, Hazard’s Corners, and Upper Lisle.
