See the Definition and Construction of a Pedal Triangle |
| 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. |  |
