    I'm not familiar with these 2 column proofs but basically because a || b the internal angles <1 and <4 , and <2 and <3 both add up to 180 degrees. So since we are given that <1 = <4 then <2 must be equal to <3.

    Hmm I'm not sure what would be the fastest way to finish this... I like welsh's idea of using the fact that we have two pairs of supplementary angles and doing some business with that. But maybe we have some trapezoid rule we can use to shorten it :o

    Since <1 and <4 are the same, hmm <2 and <3 must be the same... Bahh I dunno >.< There's probably a better way to do these last few steps... grr

    \[\large\rm V=LWH\]Notice that L is being `multiplied` by W and H. How do we undo `multiplication`? What is the opposite of multiplication?
