Question 8 • Geometry

How are the semicircle and the diameter of a circle related?

Answer
A
The length of the diameter and the length of the semicircle are the same.
B
The angle measure of the diameter is half the angle measure of the semicircle.
C
The degree measure of the diameter and the degree measure of the semicircle are the same.
D
The angle measure of the diameter is twice the angle measure of the semicircle.

Explanation

A diameter divides a circle into two semicircles. The arc of a semicircle measures 180°, and the central angle formed by the diameter’s endpoints also measures 180°. So their degree measures are the same, making choice C correct.
