A circle is divided into 5 equal parts. What is the measure of the angle that turns through 2 parts?
The entire circle is 360°.
To divide the circle into 5 equal parts, each part is 360°/5 = 72°.
Therefore, to turn through 2 parts, we need to calculate:
2 * 72° = 144°
The angle that turns through 2 parts of a circle divided into 5 equal parts is 144°.
