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

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles on opposite sides of the transversal but inside the two lines. They are equal when the lines are parallel.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles on opposite sides of the transversal but outside the two lines. They are equal when the lines are parallel.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles on the same side of the transversal and inside the two lines. They are supplementary when the lines are parallel.

Front

How do you determine if two angles are supplementary?

Back

Two angles are supplementary if the sum of their measures equals 180 degrees.

Front

What is the measure of angle a if angle b is 132 degrees and they are vertical angles?

Back

Angle a is also 132 degrees because vertical angles are equal.

Front

If angle d is 29 degrees and it is supplementary to angle f, what is the measure of angle f?

Back

Angle f is 151 degrees because 180 - 29 = 151.
