Parallel lines cut by a transversal vocabulary

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 and inside the parallel lines?

Back

Same Side Interior Angles

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 and outside the parallel lines?

Back

Same Side Exterior Angles

Front

What is the angle relationship when two parallel lines are cut by a transversal and the angles are on opposite sides of the transversal and inside the parallel lines?

Back

Alternate Interior Angles

Alternate Exterior Angles

Front

What is the angle relationship when two parallel lines are cut by a transversal and the angles are in the same position relative to the parallel lines?

Back

Corresponding Angles

Front

What is the relationship between alternate exterior angles when the two lines are parallel?

Back

Alternate exterior angles are congruent.

Front

What is the relationship between alternate interior angles when the two lines are parallel?

Back

Alternate interior angles are congruent.

Front

What is the relationship between corresponding angles when the two lines are parallel?

Back

Corresponding angles are congruent.

Front

What is the relationship between same side interior angles when the two lines are parallel?

Back

Same side interior angles are supplementary.

Front

If two lines are cut by a transversal and the alternate interior angles are congruent, what can be concluded about the two lines?

Back

The two lines are parallel.
