Use our reference angle calculator to find the reference angle for any angle in degrees or radians. Plus, learn the reference angle formulas.
Use this simple calculator to find the reference angle of any angle. Learn how to find a reference angle without a calculator.
The reference angle calculator helps you find the acute (smaller than 90 degrees) angle in the standard position between the terminal side and the x-axis of an angle. This reference angle simplifies trigonometric calculations and helps to determine the positive or negative nature of trigonometric functions.
Find the reference angle that represents the acute angle display of any angle in both degrees and radians with the help of this reference angle calculator.
When you want to recalculate angles into their acute version, then a reference angle calculator can be the best tool to have. Once you have a positive angle, you can input the data and find out the reference angle almost immediately.
When the terminal side is in the second quadrant (angles from 90° to 180° or from π/2 to π), our reference angle is 180° minus our given angle. So, you can use this formula. Reference angle° = 180 - angle. For example: The reference angle of 125 is 180 - 125 = 55°.
This online calculator is really easy to use. You can enter the angle value in the first field to find the reference angle of your desired angle. The calculator will then display the reference angle of the entered angle value when you press the calculate button.
