Parallel Lines Cut by a Transversal Review

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.

Front

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

Back

They are equal.

Front

What are alternate interior angles?

Back

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

Front

If m∠1 = 30°, what is m∠3 if ∠1 and ∠3 are corresponding angles?

Back

m∠3 = 30°.

Front

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

Back

They are equal.

Front

If m∠2 = 60° and ∠2 and ∠5 are corresponding angles, what is m∠5?

Back

m∠5 = 60°.

Front

If m∠2 = 60° and m∠5 = (x + 25), what is the value of x?

Back

x = 35.

Front

What are consecutive interior angles?

Back

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