Parallel Lines Cut by a Transversal-WBVG

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

Identify a pair of corresponding angles in the diagram.

Back

Angles 2 and 6 are corresponding angles.

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

Identify a pair of alternate interior angles in the diagram.

Back

Angles 4 and 5 are alternate interior angles.

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 (add up to 180 degrees).

Front

Identify a pair of consecutive interior angles in the diagram.

Back

Angles 4 and 5 are consecutive interior angles.

Front

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

Back

Corresponding angles are equal.

Front

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

Back

Alternate interior angles are equal.

Front

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

Back

Consecutive interior angles are supplementary.

Front

If angle 2 measures 70 degrees, what is the measure of angle 6?

Back

Angle 6 also measures 70 degrees (corresponding angles).
