Hi!
Correspdoning angles are the angles that are on the same side of the transversal lines(not the parallel) and they are not right below but like q and r.
So A is wrong because the second angle is right below the first and that's not corresponding. That's supplementary.
B would work if the angles were vqr and qrw.
D is wrong because the angles are on different sides of the transversal.
THE CORRECT ANSWER IS C.
because they are on the same side of the transversal and they have the same angle length since the other angles is straight down in the same formation as the first.
Hope this helps!
