Let the triangle ABC be any triangle. Then if P is any point in the plane, then the triangle formed by constructing perpendiculars to the sides of ABC locate three points R,S, and T that are the intersections. Triangle RST is the Pedal Triangle for Pedal Point P.

** RST** triangle is the Pedal Triangle for
Pedal Point P.
