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