Parallel Lines Cut by a Transversal II

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They 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 corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

What is the relationship between alternate exterior angles when two parallel lines are cut by a transversal?

Back

Alternate exterior angles are equal when two parallel lines are cut by a transversal.

Front

If two lines are cut by a transversal and the corresponding angles are equal, what can be concluded about the lines?

Back

If the corresponding angles are equal, the lines are parallel.

Front

If two lines are cut by a transversal and the alternate interior angles are equal, what can be concluded about the lines?

Back

If the alternate interior angles are equal, the lines are parallel.
