1) tqrs, bcde name a pair of corresponding sides. look at the 1 picture.

a) qr and cd
b)tq and be
c)ts and cd
d)rs and bc

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!
