Parallel Lines and Triangles

What is the sum of the interior angles of a triangle?

If two parallel lines are cut by a transversal, what is the relationship between the corresponding angles?

What is the measure of the missing angle if one angle is 39 degrees and the other is 101 degrees?

What do you call angles that are on the same side of the transversal and inside the parallel lines?

If two angles are supplementary, what is the sum of their measures?

What is the measure of an angle that is supplementary to a 89-degree angle?

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

If one angle measures 40 degrees, what is the measure of its corresponding angle when two parallel lines are cut by a transversal?

What is the measure of an angle that is complementary to a 39-degree angle?

What do you call angles that are opposite each other when two lines intersect?
