Parallel Lines Cut By a Transversal FLASHCARD

Front

What are supplementary angles?

Back

Angles that add up to 180°.

Front

Name the angle relationship when two parallel lines are cut by a transversal and the angles are on opposite sides of the transversal and outside the parallel lines.

Back

Alternate Exterior Angles.

Front

State the angle relationship when two parallel lines are cut by a transversal and the angles are on the same side of the transversal and inside the parallel lines.

Back

Alternate Interior Angles.

Front

What are complementary angles?

Back

Angles that add up to 90°.

Front

If angle 1 is 70°, what is the measure of angle 2 if they are supplementary?

Back

Angle 2 = 110°.

Front

If angle 3 is 45°, what is the measure of angle 4 if they are complementary?

Back

Angle 4 = 45°.

Front

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

Back

Corresponding angles are equal.

Front

If angle 5 is 130°, what is the measure of angle 6 if they are alternate interior angles?

Back

Angle 6 = 130°.

Front

What is the sum of the measures of angles on a straight line?

Back

180°.

Front

If angle 7 is 60° and angle 8 is on the same side of the transversal and outside the parallel lines, what is the measure of angle 8?

Back

Angle 8 = 120° (Alternate Exterior Angles).
