Transcribed Image Text:**Question Title: Identifying a Right Angle**
Please select the angle below that represents a right angle:
- ◯ \(\frac{3\pi}{2}\)
- ◯ \(\frac{5\pi}{4}\)
- ◯ \(\frac{\pi}{4}\)
- ◯ \(\frac{5\pi}{6}\)
A right angle is an angle of 90 degrees or \(\frac{\pi}{2}\) radians. Out of the given options, it's required to identify which value equals \(\frac{\pi}{2}\) radians.
#### Explanation of Options:
- \(\frac{3\pi}{2}\): This angle is equivalent to 270 degrees.
- \(\frac{5\pi}{4}\): This angle is equivalent to 225 degrees.
- \(\frac{\pi}{4}\): This angle is equivalent to 45 degrees.
- \(\frac{5\pi}{6}\): This angle is equivalent to 150 degrees.
Thus, none of the given options represent a right angle.
