Given a triangle and a point , the vertices of the pedal triangle of with respect to are the feet of the perpendiculars from to the sides of .[more]
Let , , be the exact trilinear coordinates (Wolfram MathWorld) of with respect to the sides , , ; let ; and let , , be Conway notation with respect to .
Then, as signed distances,
The formulas for the other two sides are analogous.[less]
