Answer 1

@anitasonia98 Last one!

Answer 2

Well, angles that opposite each other in a quadrilateral add up to 180 degrees. It's just a basic facet of quadrilaterals.

Answer 3

Again, not sure how to write a proof for this. It just is, you know?

Answer 4

So it would just be C+E=180?

Answer 5

Well, they're asking why C + E =180.

Answer 6

I guess I just write because opposite angles add up to 180 lol

Answer 7

Yep lol

Answer 8

:) Thanks so much! I'm 100% done with Geometry now!

Answer 9

Sweet! :)
