If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).
Since the angle 225° is in the third quadrant, the reference
angle formula is Ar=Ac-180°. Ar = 225° − 180°
Ar=225°-180°
The reference angle is Ar=45°
