Answer 2

I'll just do 1 at a time so if you do know them I can give you a medal for each

Answer 3

Well, I don't know... But I think I know someone who does.

Answer 5

okay! That helps a lot too

Answer 6

yes, that is an isosceles trapezoid, now wouldn't I create two altitudes forming two right triangles?

Answer 7

If so, I don't know where to go from there; if not I'm completely stuck

Answer 8

I can give you an explanation on how to do it but I'm from the UK and I'm not familiar with all the names they give the reasons in the US.

Answer 9

That's fine :)

Answer 10

I'm also doing history atm so if I don't reply right away that's why

Answer 11

Yes I think thats one way to do it.
If you can prove theses triangles are congruent then it follows that the base angles are equal.
Let me see

Answer 12

What do you want to see? There is no image. it was a written question.

Answer 13

lol! - I just meant i'm thinking!

Answer 14

oh XD
