Parallel Lines and Angle Relationships: Exam Review

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They are always the same distance apart and have the same slope.

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

What is the Corresponding Angles Theorem?

Back

The Corresponding Angles Theorem states that when a transversal intersects two parallel lines, each pair of corresponding angles is equal.

What is the Alternate Interior Angles Theorem?

Back

The Alternate Interior Angles Theorem states that when a transversal intersects two parallel lines, each pair of alternate interior angles is equal.

What is the Same Side Interior Angles Postulate?

Back

The Same Side Interior Angles Postulate states that when a transversal intersects two parallel lines, the same side interior angles are supplementary (add up to 180 degrees).

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie on the same side of the transversal and between the two lines.

Front

If angle 4 is 70 degrees, what is the measure of angle 8?

Back

Angle 8 is also 70 degrees because they are corresponding angles.
