Question

name anjeli j. date 9/16 unit 1 section 10 assignment - geometry 17 explain how you can use the relationship of consecutive interior angles to prove that two lines are parallel.

Explanation:

Consecutive interior angles are supplementary (add up to 180 degrees) when two lines are cut by a transversal and the lines are parallel. So, if we can show that the consecutive interior angles formed by two lines and a transversal are supplementary, we can conclude that the two lines are parallel.

Answer:

If consecutive interior angles formed by two lines and a transversal are supplementary, the two lines are parallel.
