Biangular coordinates

In mathematics, biangular coordinates are a coordinate system for the plane where A and B are two fixed points, and the position of a point P not on the line AB is determined by the angles PAB and PBA. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and In Mathematics and its applications a coordinate system is a system for assigning an n - Tuple of Numbers or scalars to each point
