Have you learned about lines,points, parallel lines? Have you learned about properties of a rectangle? Have you learned about rotations, reflections, translations? Tell me any and everything you have learned from the above.

One way to solve it is by graphing it (see above) Another way is to calculate the coordinates using analytic geometry, that might take 4-6 minutes. The third way is to use a 180 rotation about the centre of the rectangle, that takes about 20 seconds.
