The reference angle calculator will get the angle that is formed by the X axis and it's terminal side. For any angle, we would need to see the angle formed by its terminal side with the axis to find the reference angle. Each quadrant will have the same reference angle. This reference angle calculator will give you an instant result making your math problems easy and fast work. This also gives you the ability to find multiple angles in just a few short minutes. Below the CALCULATE button will be your REFERENCE ANGLE in DEGREES and also which quadrant the ANGLE is in. This will be the first, second, third or fourth quadrants. With any quadrant you are in, the reference angle is always less than or equal to 90 degrees. This will also go for very large angles. Reference angles are mainly used in trigonometry.
