Transversals

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What is the relationship between angle 1 and angle 3 when two parallel lines are cut by a transversal?

Back

They are corresponding angles.

Front

What is the alternate interior angle to angle 3?

Back

Angle 5.

Front

What are consecutive interior angles?

Back

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

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

If ∠2 and ∠6 are corresponding angles, what can be said about their measures?

Back

They are equal.

Front

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

Back

They are equal.
