|Exploring conditions of the Pedal Triangle|
|Considering various loci and traces|
|1a.||Let 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 (extended if necessary) locate three points R, S, and T that are the intersections.|
|Triangle RST is the Pedal Triangle for Pedal Point P.|
Use GSP to create a script for the general construction of a pedal triangle to triangle ABC where P is any point in the plane of ABC.
