- Let ABC be a triangle and PaPbPc the pedal triangle of point P.
A'B'C' the triangle bounded by the radical axes:
Which is the locus of P such that ABC, A'B'C'
H is on the locus. Perspector?
- PS see special caseAPH(signed segments) ?Let ABC be a triangle and P a pointWhich is the locus of P such that PA + PB + PC = 0
