1

Define what it means for two angles to be supplementary.

2

Identify a pair of alternate interior angles in the diagram below, where lines a and b are parallel and cut by transversal t. [Diagram: Two parallel lines a and b, cut by a transversal t, with angles labeled 1-8. Angle 3 and 6 should be alternate interior angles.]

Quick comprehension check

Two parallel lines are cut by a transversal. One angle is labeled (4x + 10)° and its corresponding angle is labeled 110°. Find the value of x. Two parallel lines are cut by a transversal. One angle is labeled (2x - 20)° and the angle next to it on the same side of the transversal is labeled 80°. Find the value of x. Two parallel lines are cut by a transversal. One angle is labeled 60° and its alternate interior angle is labeled (3x)°. Find the value of x.
