Parallel Lines Unit 3 Test Review

Front

What are parallel lines?

Back

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

Front

What is a transversal?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different lines cut by a transversal.

Front

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

Back

When two lines are parallel, corresponding angles are equal.

Front

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

Back

When two lines are parallel, alternate interior angles are equal.

Front

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

Back

When two lines are parallel, alternate exterior angles are equal.

Front

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

Back

When two lines are parallel, consecutive interior angles are supplementary (add up to 180 degrees).

Front

How can you determine if two lines are parallel using angle relationships?

Back

If a transversal intersects two lines and the corresponding angles are equal, the lines are parallel.
