Question

Two circles intersect each other at P and Q. If PA and PB are their
diameters respectively, then find ZAQB.​

Answer 1

Answer

Let 0 and O be centers of two

intersecting circle, where

Points of intersection are P and Q

and PA and PB are their diameter

respectively.

join PQ ,AQ and QB

<AQP=90° and <BQP =90°

(Angle in a semicircle is a right

angle)

Adding both these angles

<AQP +<BQP =180°

<AQB=180°

Hence, the points A, Q and B are collinear.
