What is the reference angle?
the angle between the terminal side of the angle and the x-axis.
For the first quadrant:
The reference angle = 258 - 180 = 78°
For the second quadrant:
= 180 - 78 = 102°
For the third quadrant:
= 78 + 180
= 258°
For the fourth quadrant:
= 360- 78
= 282°
Thus, the reference angles are in the first, second, third, and fourth is 78°, 102°, 258°, and 282° respectively.
