What is the locus of a point P which moves on one side of a straight line XY, so that the angle XPY is always equal to 90^o?

Correct Answer: Option D

Explanation

Since XY is a fixed line and
XPY = 90^o P is on one side of XY
P₁P₂P₃……Pⁿ are all possible cases where
XPY = 90^o the only possible tendency is a semicircle because angles in semicircle equals 90^o
