Formula & Methodology
The formula to find the coterminal angle is:
Coterminal Angle = Angle % 360
Where % represents the modulo operation.
Real-World Examples
Example 1
Find the coterminal angle of 450° and 270°.
Coterminal Angle of 450° = 450 % 360 = 90°
Coterminal Angle of 270° = 270 % 360 = 270°
Data & Statistics
| Angle 1 | Angle 2 | Coterminal Angle 1 | Coterminal Angle 2 |
|---|---|---|---|
| 450 | 270 | 90 | 270 |
Expert Tips
- Always use the modulo operation to find coterminal angles.
- Remember, the coterminal angle is always between 0° and 360°.
