Parallel Lines Cut by a Transversal

Front

What are complementary angles?

Back

Angles that add up to 90°.

Front

What is the angle relationship when two parallel lines are cut by a transversal and the angles are on the same side of the transversal?

Back

Consecutive Interior.

Front

What is the angle relationship when two parallel lines are cut by a transversal and the angles are in opposite positions?

Back

Vertical Angles.

Front

What are corresponding angles?

Back

Angles that are in the same position on parallel lines in relation to the transversal.

Front

If angle 5 is 70°, what is the measure of angle 6?

Back

Angle 6 = 70° (Alternate Interior Angles are congruent).

Front

If angle 4 is 50°, what is the measure of angle 8?

Back

Angle 8 = 50° (Corresponding Angles are congruent).

Front

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

Back

180°.

Front

If two angles are supplementary, what is their sum?

Back

180°.

Front

If angle 1 is 30°, what is the measure of angle 3?

Back

Angle 3 = 150° (Linear Pair).

Front

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

Back

They are congruent.
