Geometry Parallel Lines with Transversal

Front

What are parallel lines?

Back

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

What is a transversal?

Back

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

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines.

What are alternate exterior angles?

Back

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

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different lines when a transversal crosses them.

How can you identify parallel lines using angles?

Back

If a transversal intersects two lines and the alternate interior angles are equal, then the lines are parallel.

What is the relationship between the sum of interior angles on the same side of the transversal?

Back

The sum of the interior angles on the same side of the transversal is supplementary (adds up to 180 degrees).
