The Slope of Parallel Lines Theorem is a biconditional statement, which is that two lines are parallel if and only if they have the same slope.
Transitive Property of Equality:
1.I know that because the slope of t = m, and t = BC ⨸ AC and m = EF ⨸ DF, then BC ⨸ AC = EF ⨸ DF.
2.Rewriting this proportion yields BC ⨸ EF = AC ⨸ DF.
3.Triangle ACD and Triangle DFE have one right triangle.
I looked on Quizlet and it uses the AA triangle similarity property. But if there's no proof that any of the other two corresponding angles are congruent to each other, then the AA similarity cannot be used. Then I don't know how to prove that the line of l is parallel to the line of n.

AHHHHHH Math !!!!
I don't ever want to have to do this again :'D
Sorry i can't help you on that, i suck at this, good luck man

What math course are you taking right now?
Math is built upon foundations, so I think every single human can learn math.
