    The flow chart with missing statements and reasons proves that the measure of angle ECB is 62°.

    |dw:1348275143603:dw| What is the theorem that says the angles are congruent if the lines are parallel?

    Hey, I don't think this picture goes with this proof. D is a right angle in the diagram but not on the flow chart. Please check diagram and chart to see if they go together.

    Okay, we're back to the question I asked. State the theorem that supports how we know these two angles are congruent if the lines are parallel.

    Read page one at this link and see if you can figure out which theorem it is. http://www.nexuslearning.net/books/ml-geometry/Chapter3/ML%20Geometry%203-4%20Proving%20Lines%20are%20Parallel.pdf
