Answer

Degree measure and radian measure are both units that are used to measure an angle. A full circle has an angle of 360 degrees or $2\pi$ radians.

Work Step by Step

Degree measure and radian measure are both units that are used to measure an angle. A full circle has an angle of 360 degrees or $2\pi$ radians. We can use the conversion factor of $\frac{\pi}{180^{\circ}}$ to convert from degrees to radians. Similarly, we can use the conversion factor of $\frac{180^{\circ}}{\pi}$ to convert from radians to degrees.
