Parallel Lines Converse Flashcard

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What can we conclude about Alternate Interior Angles when two parallel lines are cut by a transversal?

Back

They are congruent (equal in measure).

Front

What can we conclude if two lines cut by a transversal have supplementary consecutive exterior angles?

Back

The lines are parallel.

Front

What is the Congruent Supplements Theorem?

Back

If two angles are supplementary to the same angle (or to congruent angles), then the two angles are congruent.

Front

What type of angle pair are ∠1 and ∠3 if they are supplementary?

Back

Supplementary angles.

Front

Define Alternate Interior Angles.

Back

Angles that lie between two parallel lines and on opposite sides of a transversal.

Front

What are Consecutive Interior Angles?

Back

Angles that lie on the same side of the transversal and between the two lines.

Front

What is the relationship between Corresponding Angles when two parallel lines are cut by a transversal?

Back

They are equal.

Front

What does it mean for two lines to be Parallel?

Back

Two lines that never intersect and are always the same distance apart.

Front

What is the definition of Vertical Angles?

Back

Angles that are opposite each other when two lines intersect. They are always equal.
