Parallel Cut by Transversal

Front

What are parallel lines?

Back

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

Front

What is a transversal?

Back

A line that crosses at least two other lines.

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines when cut by a transversal.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the parallel lines.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the parallel lines.

Front

What is the relationship between corresponding angles?

Back

They are equal when two parallel lines are cut by a transversal.

Front

What is the relationship between alternate interior angles?

Back

They are equal when two parallel lines are cut by a transversal.

Front

What is the relationship between consecutive interior angles?

Back

They are supplementary, meaning they add up to 180 degrees.

Front

If angle A is 50 degrees, what is the measure of its corresponding angle?

Back

50 degrees.

Front

If angle 1 is 135 degrees, what is the measure of angle 3 if they are corresponding angles?

Back

135 degrees.
