How do you find the reference angle?

Quadrant 1: Urgent and important.

Quadrant 2: Not urgent yet important.

Quadrant 3: Urgent but not important.

Quadrant 4: Not urgent and not important.

Can reference angles ever be negative?

The sign depends on the quadrant of the original angle. The trigonometric function values for the original angle will be the same as those for the reference angle, except for the positive or negative sign, which is determined by x – and y -values in the original quadrant.
