Pedal Circle of Isogonal Conjugates
- Steve Phelps
Take any point and drop perpendiculars from the point to the sides (possibly extended). The feet of the perpendiculars lie on the PEDAL CIRCLE of the point. Take two points that are ISOGONAL CONJUGATES (P and Q). They have the same pedal circle. The center of the circle is the midpoint of the two conjugate points (J).
