How to Find Reference Angles?
Rules for reference angles in each quadrant Steps to find reference angles Find the coterminal angle of the given angle that lies between \(0°\) and \(360°\). If the angle of step \(1\) is between \(0\) and \(90°\), that angle itself is the reference angle of the given angle. If not, then we need to check if it is […]
