Ineed the answer to this asap. you just need to match each thing on the left to its correct answer on the right.
match the following items.

complete the proof for theorem 3-13. (if you dont know what this theorem is i added a picture that explains it so you can )

The only thing is with this one... I don't have an image showing where angles 1 2 3 4 are.

But I'll give it a try:

1) l // m ___ Given

2) <1 = <3 ___ if parallel lines, then corresponding angles (<s) are equal

3) <2 = <3 ___ Vertical <s are equal

4) <1 = <2 ___ Substitution

Hope i can you!
