Parallel Lines Cut By A Transversal

Front

What are parallel lines?

Back

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

Front

What is a transversal?

Back

A line that crosses two or more 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 alternate exterior angles?

Back

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

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect.

Front

If two parallel lines are cut by a transversal, what can we say about the corresponding angles?

Back

They are equal.

Front

If angle 1 is 70°, what is the measure of angle 5 if angle 1 and angle 5 are corresponding angles?

Back

70°.

Front

What is the sum of the angles on a straight line?

Back

180°.

Front

If angle 2 is 38°, what is the measure of angle 3 if angle 2 and angle 3 are alternate interior angles?

Back

38°.
