Question

Please try to help me with geometric proofs.

Use a paragraph proof to prove the corresponding angles postulate:

Given: AB is parallel to CD

Prove: Corresponding angles are congruent

Answer 1

Corresponding angles are \(1\) and \(5\), \(2\) and \(6\), \(4\) and \(8\), and \(3\) and \(7\). They are congruent simply because of the fact that lines \(AB\) and \(CD\) are parallel. What is the format of the proof you are expected to submit?

Answer 2

Well I'm not allowed to use the what your trying to prove in your response so I can't say they are corresponding angles.

Answer 3

@across and what do you mean by the format of the proof that I'm expected to submit ?

Answer 4

@experimentX Please try to help me if your not busy.

Answer 6

@experimentX Thats incorrect because they are saying draw lines and talking about perpendicular. I have to prove that corresponding angles are congruent and im given that AB is parallel to CD not perpendicular.

Answer 7

1# 4 = 6 (alternate angle)
2# 6 = 8 (vertically opp angle)
3# 4 = 8 from #1 and #2 (hence corresponding angles are equal

Answer 8

Thanks so much I really appreciate it.
