Parallel Lines and Transversal

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal. They are congruent.

Front

What does the Corresponding Angles Theorem state?

Back

The Corresponding Angles Theorem states that if two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are angles that lie between two parallel lines and on opposite sides of a transversal. They are congruent.

Front

What is the relationship between alternate exterior angles?

Back

Alternate exterior angles are angles that lie outside two parallel lines and on opposite sides of a transversal. They are congruent.

Front

What are same-side interior angles?

Back

Same-side interior angles are angles that lie between two parallel lines and on the same side of a transversal. They are supplementary.

Front

What is the Linear Pair Postulate?

Back

The Linear Pair Postulate states that if two angles form a linear pair, then they are supplementary, meaning their measures add up to 180 degrees.
