Choose the point on the terminal side of -45°.

I read my lesson, and I'm a bit confused. I read about reference angles and how there's a rule for angles greater than 90 degrees and less than 0 degrees. Since the angle given was -45 degrees, my first step was adding 360 to get a positive 315. Since 315 is in the 4th quadrant, I did 360-315 and got a positive 45 degrees. I'm not really sure where to go from there. If someone could explain where to go from here or where I went wrong and how to fix it, I would greatly appreciate it.
