A reference angle is the acute angle between the terminal side of an angle and the nearest x-axis. In other words, it is the angle between the positive x-axis and the terminal side of an angle. This concept is essential in trigonometry, as it allows us to find the sine, cosine, and tangent values of any angle using the unit circle. For example, if we have an angle of 300 degrees, we can find its reference angle by subtracting 300 from 360, resulting in a reference angle of 60 degrees. This makes it possible to determine the sine, cosine, and tangent values of 300 degrees using the corresponding values of 60 degrees.

Reality: Reference angles can be used for both positive and negative angles.

Myth: Reference angles are only for negative angles.
