Geometry ! will give brainliest stars and you!

1) c- you have to imagine if you folded it and have b and f where they are pictured on the right
2) a- supplementary angles add up to 180°

On number 1, look at where B and F are and compare it to the net. That should help you.

On number 2, what makes a supplementary or complementary angle?

I hope this helps you. Please don't cheat on an exam.

Best wishes and good luck to you! - kaikerscupcake <3
