Helena stopped at Checkpoint C, which has coordinates (−4,5). She gets to Checkpoint D at (−3,2) by crawling underneath barbed wire. She will have to crawl underneath barbed wire between the next two checkpoints (E and F) as well. What are the coordinates of Checkpoints E and F if EF¯¯¯¯¯¯¯¯ is located at CD¯¯¯¯¯¯¯¯’s location in a 180∘ rotation of the course?

E(−4,5)
E(−4,−5)
F(3,2)
F(−3,2)
F(3,−2)
