Let's suppose that there CAN be 2 perpendiculars from one point to a particular line segment.
This would mean that in triangle POQ, angle P would be equal to zero degrees by angle sum property, which is not possible.
Thus, we arrive at a contradiction, thus there is only 1 perpendicular possible from one point to another line.
