The reference angle calculator finds the corresponding angle in the first quadrant.

A chosen reference angle (right angle, straight angle or full angle) can be divided into equal parts, and the size of one part used as a unit for measurement of other angles.

An angle measured in the counterclockwise (anti-clockwise) direction is a positive angle. In other words, positive angles are those angles that are rotated from the base in the anti-clockwise direction.

There are two main ways to label angles: 1. give the angle a name, usually a lower-case letter like a or b, or sometimes a Greek letter like α (alpha) or θ (theta) 2. or by the three letters on the shape that …

Calculate any trigonometric function by inputting the angle at which you want to evaluate it; and Solve for the sides or angles of right triangles by using trigonometry.
