Original Khojo Papers practice question — not from a past board paper.
The first locus is the perpendicular bisector of AB and the second is the bisector of angle A; P is the point where they cross.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
The construction needs a pair of compasses only: equal arcs from A and B for the perpendicular bisector, and equal arcs on AB and AC from A for the angle bisector.
