Biangular coordinates are a type of coordinate system used primarily in two-dimensional geometry. In this system, each point in the plane is represented by a pair of angles, rather than traditional Cartesian coordinates (x, y) or polar coordinates (r, θ). Specifically, a point is defined by two angles, (α, β), which are measured from two fixed lines or reference directions.
