The coterminal angle of -566° within 0° to 360° is -206°. The original angle is in the third quadrant (180° to 270°), with a reference angle of 26° formed by the terminal side and the nearest x-axis.
To find the coterminal angle, quadrant, and reference angle for the angle
, follow these steps:
1. Coterminal Angle:
- To find a coterminal angle within the range
, you can add or subtract multiples of

-

- The coterminal angle within the given range is

2. Quadrant:
- The original angle
is in the third quadrant.
- Since one full revolution is
, each quadrant is
, and the third quadrant is from

3. Reference Angle:
- The reference angle is the acute angle formed by the terminal side of the angle and the x-axis.
- Since the angle is in the third quadrant, the reference angle is the angle between the terminal side and the nearest x-axis, which is

So, for the angle

- Coterminal angle:

- Quadrant: Third quadrant
- Reference angle:

The probable question may be:
For the rotation -566\deg , find the coterminal angle from 0\deg <=\theta <360\deg , the quadrant, and the reference angle.
