Question

prove that angle inscribed in semicircle is right angle​

Answer 1

Answer:

Now POQ is a straight line passing through center O.

∴ Angle subtended by arc PQ at O is

∠POQ=180°

The angle subtended by an arc at the center is double the angle subtended by it any point on the remaining part of the circle.

∴∠POQ=2∠PAQ

∠POQ

=∠PAQ
