Make-Up 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 crosses at least two other lines.

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are supplementary angles?

Back

Two angles that add up to 180°.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines cross.

Front

If ∠7 and ∠8 are supplementary, what is their sum?

Back

180°.

Front

Name the corresponding angle to ∠4.

Back

∠8.

Front

If ∠3 is 64°, what is the measure of its alternate interior angle?

Back

64°.

Front

If two angles are vertical, what can you say about their measures?

Back

They are equal.
