@johnweldon1993 can u please help me !!!

Do you have the original question?

yes I am (:

Good, so this is what we're given with.
|dw:1433891186196:dw|
We need to prove that AD // BC

* we need to prove that mAD = mBC

@Moo_Moo17
What do you think the approach would be?

im not sure I feel like I know it but I cant remember sorry im trying

You still need 3 justifications that I left blank to complete the proof.

oh ok so so the 1 is ASA I think
2 m not to sure what it would be
3 SSS I think

im trying to figure it out but im having trouble can u please help me I don't understand

I sorta have I wasn't very good at it

and this one for congruent angles:

Consider the above diagram.

@Moo_Moo17 you there?

yea i am sorry

No sorry, it took me a while to come back, sorry about that.

Seeing that BC is parallel to AD, what can you say about angles ADB and DBC?

They are equal, because they are alternate interior angles. (read the second link)

Here is a guide to show you that one pair of sides are congruent. I leave the rest of the proof for you to do on your own. You'll have similar steps to mine that I show in the attached pdf.

BC is congruent to AD but also i think they are corresponding angles or transversal

AD is equal to AD with the justification "common", because it's the same length.
