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.
To measure an angle of over 90Â°, subtract the number of degrees as indicated on the dial from 180Â°, as the dial is graduated from opposite zero marks to 90Â° each way. Since the spaces, both on the main scale and the Vernier scale, are numbered both to the right and to the left from zero, any angle can be measured.
