Let P̅Q be the perpendicular to the line segment X̅Y. Let P̅Q and X̅Y intersect in the point A. What is the measure of∠A

Construct the perpendicular bisector of the line segment PQ.

l is the perpendicular bisector of the line segment PQ and R is a point on the some side of l as P. The line segment QR intersects l at X. Prove that PX + XR = QR .

In Figure,AP and BQ are perpendiculars to the line segment AB and AP=BQ. Prove that O is the mid-point of line segment AB and PQ. Figure
