Let ΔPQR be the pedal triangle of ΔABC. Excenters of ΔPQR are (20,8),(4,12),(13,1).
If one of the vertices of ΔPQR is (14,2), then find the area of ΔABC.
Details and Assumptions:
- Pedal triangle of a triangle is formed by joining feet of altitudes to the sides of the triangle.
- An excenter of a triangle is a point of intersection of an internal angle bisector and two external angle bisectors of the triangle.
