What do you need to show to prove lines are parallel?

?

That's what I have so far

But the picture doesn't look like that.

Let's look at your figure, and reason out the steps in this proof.

Yes.

I marked the parallel lines and the given congruent angles.
|dw:1434569202980:dw|

We know angles 1 and 6 are congruent.
We need to show that angles 2 and 6 are congruent.

Exactly. That is it.

then 6 and 4 are congruent (vertical angles), so 4 is congruent to 1 and 2 (transitive property)

is that useful?

No. There is no need for 6 and 4

okay.

Now what?

This is simpler proof than you originally thought.

we can prove that they're parallel with 2 and 6?

I'll go through your steps and we'll see what needs to be there.

Okay.

I'd keep statement 1, drop statements 2, 3.
Keep statement 4.

Drop statement 5.

keep statement 6 and 7

then drop 8 and add in the part about corresponding angles?

Okay. Thank you so much!

You're welcome.
