What is the Alternate Exterior Angle Converse Theorem

The video tutorial explains the relationship between alternate exterior angles and parallel lines. It begins with a brief mention of alternate and consecutive interior angles, then focuses on alternate exterior angles, explaining that if these angles are congruent, the lines they intersect are parallel. The tutorial concludes with a recap of these concepts.

What does it mean when alternate exterior angles are congruent?

• They are different in measure.

• They are equal in measure.

• They are supplementary.

• They are complementary.

What can be concluded if two lines are intersected by a transversal and the alternate exterior angles are equal?

• The lines are skew.

• The lines are intersecting.

• The lines are parallel.

• The lines are perpendicular.

Which of the following is true about alternate exterior angles and parallel lines?

• If alternate exterior angles are equal, the lines are perpendicular.

• Alternate exterior angles are always complementary.

• If alternate exterior angles are equal, the lines are parallel.

• Alternate exterior angles are always supplementary.

How can you determine that two lines are parallel without explicitly stating it?

• By showing the lines are intersecting.

• By showing alternate exterior angles are equal.

• By showing the lines are skew.

• By showing the lines are perpendicular.

What is the significance of showing two alternate exterior angles as equal?

• It proves the lines are perpendicular.

• It proves the lines are intersecting.

• It proves the lines are skew.

• It proves the lines are parallel.
