Parallel Lines Cut by a Transversal

What are alternate exterior angles?

• Pairs of angles that lie inside the two parallel lines and on the same side of the transversal.

• Pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal in measure.

• Pairs of angles that lie outside the two parallel lines and on the same side of the transversal.

• Pairs of angles that lie inside the two parallel lines and on opposite sides of the transversal.

What is the name of the angle pair on the same side of the transversal and inside the parallel lines?

• Alternate interior angles

• Consecutive interior angles

• Corresponding angles

• Exterior angles

True or False:
Alternate interior angles are always congruent when two parallel lines are cut by a transversal.

• True

• False

• Sometimes

• Only in specific cases

If one alternate exterior angle measures 120°, what is the measure of the other alternate exterior angle?

• 100°

• 120°

• 130°

• 140°

How do you identify alternate interior angles?

• They are angles that lie outside the parallel lines.

• They are pairs of angles that lie between the two parallel lines and on opposite sides of the transversal. They are equal in measure.

• They are angles that are on the same side of the transversal and inside the parallel lines.

• They are angles that are formed by the intersection of two lines.

What is the measure of a right angle?

• 45°

• 90°

• 180°

• 360°

What is the relationship between the angles formed by a transversal cutting two parallel lines?

• The angles formed include only corresponding angles.

• The angles formed include alternate interior angles, alternate exterior angles, corresponding angles, and consecutive interior angles.

• The angles formed are all equal to 90 degrees.

• The angles formed are all supplementary to each other.

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

• Adjacent angles

• Complementary angles

• Vertical angles

• Supplementary angles

If one corresponding angle measures 75°, what is the measure of its corresponding angle?

• 60°

• 75°

• 90°

• 45°

A transversal cuts two parallel beams on a bridge. If one angle is 85°, what is the measure of its corresponding angle?

• 75°

• 85°

• 90°
