An isogonal mapping is a transformation that preserves the magnitudes of local angles, but not
their orientation. A few examples are illustrated above.
A conformal mapping is an isogonal mapping that also preserves the orientations of local angles. If is a conformal mapping, then is isogonal but not conformal. This is due to the fact
that complex conjugation is not an analytic
function.
