Answer:
Step-by-step explanation:
Ok so I'm doing this on my phone so it's a bit difficult. 180 degrees either way is really just flipping the image upside down. So when you are flipping this around the midpoint, and it's a line, you can just picture it as if you are switching the 2 end points, so switch c and d mentally and that should be your answer. I hope this helps if not, I'm sorry
