Answer:
This was translated 180 degrees clockwise around the origin.
Explanation:
In order to find this, simply look for where the point is from it's original point. You'll notice that each point changes into the quadrant diagonal from it's original quadrant. Since this happens with each one, we know it must rotate roughly 180. Also, since each line is parallel to it's original spot, it is exactly 180 degrees around the origin.
