Are you able to follow the steps they show in the left column?

e.mccormick · Answer

By drawing the first steps it can make it easier.  You can then visually see what they are doing on the left side that you need to momic on the right.

anonymous · Answer

can you explain it a little more?

e.mccormick · Answer

Well, in the left column, see how it says $\angle MLK \cong \angle PML$ ?  So you could draw that in and see the relationship they mean for alternate interior.

Also note that they went from $\angle MLK \cong \angle PML$ in the third on the left to $\angle PML \cong \angle KJM$ in the fifth.  That means $\angle PML$ becomes the bridge between.

Well, if you do the same thing on the right, then the fifth thing on the right has the bridge angle in it that you need to put in the third thing (1.______) on the right.

e.mccormick · Answer

Here is what I mean visually.  It shows how a little logic lets you see what is missing.

anonymous · Answer

so is it b or d?

e.mccormick · Answer

Quite likely.  Just draw things in on the sketch or make your own on paper and you should have everything you need.

anonymous · Answer

okay thank you so much you were such a great help!

e.mccormick · Answer

np.  

I find that a quick sketch can really help these sort of problems.  Lets you keep track of what the proof means because you can mark it all up and see if it makes sense.  That is because geometry and trig are very visual parts of math.
