Question

measure of angle inscribed in a semicircle is

• A. ${90}^0$
• B. ${120}^0$
• C. ${100}^0$
• D. ${60}^0$

Answer 1

The correct option is A ${90}^0$

The intercepted arc for an angle inscribed in a semi-circle is ${180}^{\circ }$.

Therefore the measure of the angle should be half of ${180}^{\circ }$, or ${90}^{\circ }$.

The angle is a right angle.
