Question

Make a conjecture about the measures of Consecutive Interior Angles formed by parallel lines and a transversal

Answer 1

I believe they will be supplementary. They will actually look something like this: _________/_______ (but upside down) with the / being the transversal and the ___ being one of the parallel lines. On either side of the transversal is an interior angle. Consecutive means they are side by side, so they must be supplementary. Supplementary means that the sum of both angles, when added together, will equal 180 degrees.
