Definition: The smallest angle that the terminal side of a given angle makes with the x-axis. Try this: Adjust the angle below by dragging the orange point around the origin, and note the blue reference angle. In the figure above, as you drag the orange point around the origin, you can see the blue reference angle being drawn.
WebbThen, they would also know the trig ratios for angle measuring 30 + 45 = 75, 45 − 30 = 15 , and 45 + 45 + 30 = 130 degrees, for example. If such a person also knew the sine and … WebbRule: Subtract the smaller bearing from the greater one. The difference will give the interior angle if it is less than 180°. But if the difference exceeds 180°, It will be exterior angle. Then obtain the interior angle by subtracting the difference from 360°. (b) When bearings of the two lines measured not from their point of ...
