Constructing a Pedal Triangle
Rita Meyers

In order to construct a pedal triangle we start out with triangle ABC and an arbitrary point P

Then construct a perpendicular line to side AB of the triangle through point P with the point of intersection being point R

We then construct a line perpendicular to side BC through the point P with it's intersection labeled as point S

And lastly construct a perpendicular line to side CA through point P labeling the intersection point T

Construct line segments connecting points RST to form triangle RST; better known as the pedal triangle
