See a graph with the four quadrants and the trigonometric functions, and a table of common angles and their reference angles. A reference angle is the acute angle formed between the terminal side of an angle in standard position and the x-axis. It serves as a reference point to determine the exact values of trigonometric functions, such as sine, cosine, and tangent . Reference angles are used to simplify complex calculations and reduce problems to a manageable form.

A reference angle is the positive acute angle formed between the terminal side of an angle and the nearest x-axis in a Cartesian coordinate system. In other words, the reference angle is that angle sandwiched between the terminal side and the x-axis and it always falls between 0 and 90 degrees.

Reference angles, by definition, always have a measure between 0 and . Due to the periodic nature of the trigonometric functions, the value of a trigonometric function at a given angle is always the same as its value at that angle's reference angle, except when there is a variation in sign.
