What is a Reference Angle?

• Draw the terminal side of the angle.

Reference angles are used to measure the distance between a point on the coordinate plane and the nearest x-axis or y-axis. In trigonometry, reference angles are used to find the values of sine, cosine, and tangent functions. For example, if a point has coordinates (x, y), the reference angle is the angle between the point and the nearest x-axis. Understanding reference angles is essential in solving trigonometric problems, particularly in right triangles.
