Question

value: 1
true or false? a semi - circle is 90°.
true
false

Explanation:

Step1: Recall circle angle measure

A full - circle has an angle measure of 360°.

Step2: Calculate semi - circle angle

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

Answer:

False
