Midterm Pretest #1

Front

What are Linear Pairs?

Back

Linear pairs are two adjacent angles that form a straight line. They are supplementary, meaning their measures add up to 180 degrees.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. If the lines are parallel, these angles are congruent.

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. If the lines are parallel, these angles are congruent.

Front

What are Alternate Exterior Angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal. If the lines are parallel, these angles are congruent.

Front

What are Same Side Interior Angles?

Back

Same side interior angles are pairs of angles that lie between two parallel lines and on the same side of a transversal. If the lines are parallel, these angles are supplementary.

Front

What is the Vertical Angle Theorem?

Back

The Vertical Angle Theorem states that opposite angles formed by two intersecting lines are congruent.

Front

What is the Corresponding Angles Postulate?

Back

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

Front

What is the Alternate Interior Angle Theorem?

Back

The Alternate Interior Angle Theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles is congruent.

Front

What is the definition of Congruent Angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the definition of Supplementary Angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.
