Can reference angle be negative
To find the reference angle of a negative angle, we have to add 360° or 2π to it as many times as required to find its coterminal angle. For example, to find the reference angle of -1000°, we will add 360° three times to it. It implies, - 1000° + 3 (360°) = -1000° + 1080° = 80°.
