False
As we know that a perpendicular bisector divides a line segment into two equal parts.
So, if A (2, 7) lies on perpendicular bisector of P (6, 5) and Q (0, - 4),
Then AP = AQ
By distance formula;

As we can see AP ≠ AQ
Hence, the point A (2, 7) does not lie on the perpendicular bisector of the line segment PQ.
