Front

What type of angle pair are ∠1 and ∠3 when parallel lines are cut by a transversal?

Back

Supplementary angles.

Front

What is the relationship between corresponding angles when parallel lines are cut by a transversal?

Back

They are congruent.

Front

Define supplementary angles.

Back

Angles that add up to 180°.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are congruent.

Front

Which angles are congruent when two parallel lines are cut by a transversal?

Back

Corresponding angles.

Front

What is the sum of the interior angles on the same side of a transversal when parallel lines are cut?

Back

They add up to 180°.

Front

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

Back

They are congruent.

Front

What is the relationship between same-side interior angles when parallel lines are cut by a transversal?

Back

They are supplementary.

Front

If angle 5 is 70°, what is the measure of angle 6 if they are corresponding angles?

Back

Angle 6 is also 70°.

Front

What is the definition of corresponding angles?

Back

Angles that are in the same position on parallel lines in relation to the transversal.
