An angle’s reference angle is the measure of the smallest, positive, acute ...When the terminal side of the given angle is in the second quadrant (angles from 90° to 180°), our reference angle is calculated by subtracting the given angle from 180 degrees. So, you can use the formula below: Reference angle° = 180 - angle. Thus, the reference angle of 143° = 180 - 143 = 37°. Important: the angle unit is set to degrees.

The thing which can sometimes be confusing is the difference between the reference angle and coterminal angles definitions. Remember that they are not the same thing – the reference angle is the angle between the terminal side of the angle and the x-axis, and it's always in the range of [ 0 , 90 ° ] [0, 90\degree] [ 0 , 90° ] (or [ 0 , π ...The reference angle is the angle that the given angle makes with the x-axis. When the terminal side of the given angle is in the second quadrant (angles from 90° to 180°), our reference angle is calculated by subtracting the given angle from 180 degrees. So, you can use the formula below: Thus, the reference angle of 136° = 180 - 136 = 44°.The positive acute angle formed between the terminal side and the \(x\)-axis is the reference angle, and the right triangle is the reference triangle.
