Parallel Lines Cut by a 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 intersects two or more lines at different points.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal; they are equal.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines; they are equal.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two lines; they are equal.

Front

What are same side interior angles?

Back

Angles that are on the same side of the transversal and inside the two lines; they are supplementary.

Front

If m∠5 = 132° and m∠6 is corresponding, what is m∠6?

Back

m∠6 = 132°.

Front

If m∠VUX = 156°, what is m∠SUT if they are corresponding angles?

Back

m∠SUT = 156°.

Front

If m∠5 = 132° and m∠6 is alternate interior, what is m∠6?

Back

m∠6 = 48°.

Front

What is the relationship between same side interior angles?

Back

They are supplementary, meaning their sum is 180°.
