To convert degrees to radians, you can use the conversion factor \( \frac{\pi \text{ radians}}{180 \text{ degrees}} \).
For an angle of 90 degrees, the conversion to radians is:
\[
90 \text{ degrees} \times \frac{\pi \text{ radians}}{180 \text{ degrees}} = \frac{90\pi}{180} = \frac{\pi}{2} \text{ radians}
\]
Therefore, the radian measure of a 90-degree angle is \( \frac{\pi}{2} \) radians.
For an angle of 90 degrees, the conversion to radians is:
\[
90 \text{ degrees} \times \frac{\pi \text{ radians}}{180 \text{ degrees}} = \frac{90\pi}{180} = \frac{\pi}{2} \text{ radians}
\]
Therefore, the radian measure of a 90-degree angle is \( \frac{\pi}{2} \) radians.
