Question

question 2 of 10 what angle measure does a semicircle have? a. 360° b. 90° c. 180°

Explanation:

Step1: Recall circle angle measure

A full - circle has an angle measure of $360^{\circ}$.

Step2: Calculate semicircle angle

A semicircle is half of a circle. So, the angle measure of a semicircle is $\frac{360^{\circ}}{2}=180^{\circ}$.

Answer:

C. $180^{\circ}$
