उत्तर
In ΔPQS,
PS < PQ ....(Of all the straight lines that can be drawn to a given straight line from a point outside it, the perpendicular is the shortest.)
I.e. PQ > PS
Also, QS < QP ....(Of all the straight lines that can be drawn to a given straight line from a point outside it, the perpendicular is the shortest.)
i.e. PQ > QS.
