Biangular coordinates

In mathematics, biangular coordinates are a coordinate system for the plane where and are two fixed points, and the position of a point P not on the line is determined by the angles and [1]

The sine rule can be used to convert from biangular coordinates to two-center bipolar coordinates.

Applications

Biangular coordinates can be used in geometric modelling and CAD. [2] [3]
