"WebAngles Greater than or Equal to 360° If the angle is equal to or greater than 360°, we have to divide the given angle by 360 and take the remainder. For example, (i) Let us consider the angle 450°. When we divide 450° by 360, we get the remainder 90°. Therefore, 450° = 90° (ii) Let us consider the angle 360° " - Trigo angle formula
