Isogonal trajectory
In mathematics an orthogonal trajectory is a curve, which intersects any curve of a given pencil of (planar) curves ''orthogonally''.
For example, the orthogonal trajectories of a pencil of ''concentric circles'' are the lines through their commo ...

Isogonal conjugate __notoc__
In geometry, the isogonal conjugate of a point with respect to a triangle is constructed by reflecting the lines about the angle bisectors of respectively. These three reflected lines concur at the isogonal conjugate of . (Th ...
