Perpendiculars from a Point on the Line between the Endpoints of the Angle Bisectors
Perpendiculars from a Point on the Line between the Endpoints of the Angle Bisectors
Let ABC be a triangle. Let AA' and BB' bisect the angles CAB and ABC. Let P be a point on A'B' and PQ be perpendicular to AB. Let PB'' and PA'' be perpendicular to AC and BC. Then PQ = PA'' + PB''.
