The corresponding sides are A) QR and CD
Why?
Those two sides are corresponding because they are the same sides of different shapes. To help you further understand, I attached an image. All of the sides with same colors are corresponding sides. For example the greens are corresponding, the reds, and purples. The blues would be corresponding as well and that is your answer. The reason the other options aren't the answers is because they are different sides. I hope this makes sense and I hope this helps!
