Answer
One-fourth of a revolution = 90° (a right angle).
- Full revolution = 360°
- 360° ÷ 4 = 90°
| Fraction | Angle |
|---|---|
| 1 revolution | 360° |
| 1/2 | 180° (straight angle) |
| 1/4 | 90° (right angle) |
| 1/8 | 45° |
| 1/3 | 120° |
One-fourth of a revolution equals 90°, known as a right angle, since a full revolution spans 360°.
