### Coterminal Angles:How to calculate coterminal angles

Coterminal angles are two angles that are drawn in the standard position (so their initial sides are on the positive x-axis) and have the same terminal side like 110° and -250° Another way to describe coterminal angles is that they are two angles in the standard position and one angle is a multiple of 360 degrees larger or smaller than the other.

### Degrees as a unit of angle measure - Math Open Reference

Measure of an angle. In geometry, an angle. is measured in degrees, where a full circle is 360 degrees. A small angle might be around 30 degrees. Usually, when a finer measure is needed we just add decimal places to the degrees. For example 45.12° The small circle after the number means "degrees".

### Reference Angle (solutions, examples, videos)

Example. Determine the reference angle that corresponds to each of the following angle. a) 165 b) 249 c) 328 Solution:a) 165 is in quadrant II (90 < 165 < 180 ) The reference angle is 180 165 = 15 Reference Angle Calculator - Calculator AcademyNext, the quadrant that this angle lays in must be determined. The quadrant that an angle is in changes every 90 degrees. Therefore, this angle would be in the second quadrant. Finally, the angle must be put into the formula above to calculate the reference angle. So RA = ABS (180-120) = ABS (60) = 60. We find that the reference angle is 60

### Reference Angle Calculator Pi Day

When an angle is negative, we move the other direction to find our terminal side. This means we move clockwise instead of counterclockwise when drawing it. Or we can calculate it by simply adding it to 360°. For instance, if our given angle is 110°, then we would add it to 360° to find our positive angle of 250° (110° + 360° = 250°).
