WebApr 14, 2024 · Depending on whether your initial angle is in the first, second, third, or fourth quadrant, there are four formulas to calculate the reference angle. If the initial angle is between 0° and 90° (first quadrant), use the formula below. If the initial angle is between 90° and 180° (second quadrant), use the formula below. Web1. If angle A is in quadrant I then the reference angle A r = A . 2. If angle A is in quadrant II then the reference angle A r = 180° - A if A is given degrees and A r = π - A if A is given in radians. 3. If angle A is in quadrant III then the reference angle A r = A - 180° if A is given degrees and A r = A - π if A is given in radians. 4.

WebSep 14, 2024 · A reference angle, denoted θ ^, is the positive acute angle between the terminal side of θ and the x -axis. The word reference is used because all angles can refer to QI.
