Question

Proove curcle subt eff nds right angle in semicircle​

Answer 1

Prove that the angle in a semicircle is a right angle.

∴∠AOB=2∠APB (∠AOB is the subtended at center which is equal to 180∘ and ∠APB is the angle made at any point on the circle.) Hence, it can be said that the angle in a semicircle is a right angle.
