Trig reference angles
WebThere will always be two angles with the same trig ratio (except for quadrantal angles), and they will have the same reference angle. We can construct reference triangles for angles in any of the four quadrants, and the trig ratios of the angle are the same as the trig ratios of its reference angle, up to sign.
