WebTerminal side is in the third quadrant. When the terminal side is in the third quadrant (angles from 180° to 270° or from π to 3π/4), our reference angle is our given angle minus 180°. So, you can use this formula. Reference angle° = 180 - angle. For example: The reference angle of 190 is 190 - 180 = 10°. WebApr 15, 2013 · Table 2 shows the results of the spectral angle mapping. The first line presents the eight HCRF curves adopted as a reference, and the first column lists the 12 tests that were classified. The numbers in bold correspond to the smallest angles determined between a test spectrum relative to each reference spectrum.
