Quadrantal angles (0, 90, 180, and 270 degrees), and the values of the sine, cosine, and tangent of each of these angles. From the trig lessons in the Algebra 2 course by Derek Owens.
You find that 360 â 350 = 10, so the reference angle is 10 degrees. Sometimes angle measures donât fit neatly in the ranges shown in the table. For example, you may need to find the reference angle for a negative angle or a multiple of an angle. To find the reference angle for â340 degrees: Determine the quadrant in which the terminal side lies. A â340-degree angle is equivalent to a 20-degree angle.
