Practice
2 questions
Two parallel lines are intersected by a transversal. One of the angles formed is 65°. Explain how you can find the measure of all the other angles formed by the parallel lines and the transversal. List the measures of all 8 angles.
Imagine a street map where two streets run parallel to each other. A crosswalk cuts across both streets at an angle. If the angle between the crosswalk and one street is 115°, what is the angle between the crosswalk and the other street on the same side of the crosswalk? Explain your reasoning using angle relationships.

Quick comprehension check
“Two parallel lines are intersected by a transversal. One angle measures 125°. Find the measure of the angle x, if angle x is supplementary to the 125° angle. Two parallel lines are intersected by a transversal. One angle measures 62°. Find the measure of the angle x, if angle x is an alternate interior angle to the 62° angle. Two parallel lines are intersected by a transversal. One angle measures 48°. Find the measure of the angle x, if angle x is a corresponding angle to the 48° angle.”
