Question

in this activity you will: find the measure of central angles and arcs. value: 1 true or false? a semi - circle is 90°. true false # 2 / 7 < prev next >

Explanation:

Step1: Recall circle angle measure

A full - circle has a central angle measure of 360°.

Step2: Calculate semi - circle angle

A semi - circle is half of a full - circle. So the central angle of a semi - circle is $\frac{360^{\circ}}{2}=180^{\circ}$, not 90°.

Answer:

False
