I will give a metal to anyone who can correctly explain/do this question! Use a paragraph proof to prove the corresponding angles postulate: Given: Line AB is parallel to line CD Prove: Corresponding angles are congruent

@Hero Can you help me? Or can anyone help me please???

It would be helpful to know what theorems you have already had and can therefore use. Have you had the theorem that says "if two parallel lines are cut by a transversal, the alternate interior angles are congruent"?

OpenStudy (lexipoo1998):

No i was not given any proofs

OpenStudy (lexipoo1998):

theorems

OpenStudy (mertsj):

That is not what I asked. You are taking geometry, right?

OpenStudy (mertsj):

Ok. I will just assume you have had some stuff.

OpenStudy (lexipoo1998):

Actually being honest I do not recall having any postulates or theorems on this subject. And yes I am taking geometry

OpenStudy (lexipoo1998):

I mean I have had them before but only on shapes.

line EF gose through both line AB and CD at the same angle their for if line AB and CD are parilel then the corisponding angles hafe to be congruent

OpenStudy (mertsj):

Angles 3 and 5 are congruent because they are alternate interior angles. Angles 5 and 7 are congruent because they are vertical angles. Angles 3 and 7 are congruent because they are equal to the same angle Angles 3 and 7 are corresponding angles Therefore, if two parallel lines are cut by a transversal, the corresponding angles are congruent.

OpenStudy (lexipoo1998):

Oh my goodness. You are amazing! Thank you soooo much!

OpenStudy (anonymous):

who me

OpenStudy (anonymous):

or mertsj

OpenStudy (mertsj):

yw

OpenStudy (lexipoo1998):

No Mertsj. Mertsj explained very well so now i understand it but thank you as well cmm
