Parallel/ Transversal Angles

Front

What are parallel lines?

Back

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

What are transversal lines?

Back

A transversal is a line that crosses at least two other lines in the same plane.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

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.

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.

What is the relationship between parallel lines and corresponding angles?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is equal.

What is the relationship between parallel lines and consecutive interior angles?

Back

If two parallel lines are cut by a transversal, then each pair of consecutive interior angles is supplementary (adds up to 180 degrees).
