Angle Relationships When Parallel Lines are Cut by a Transve

Front

What are corresponding angles?

Back

Corresponding angles are pairs of 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

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

What are vertical angles?

Back

Vertical angles are pairs of angles that are opposite each other when two lines intersect. They are equal in measure.

Front

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

Back

The corresponding angles are equal.

Front

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

Back

The alternate interior angles are equal.

Front

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

Back

The alternate exterior angles are equal.

Front

If angle 1 is 50 degrees, what is the measure of angle 5 if they are corresponding angles?

Back

Angle 5 is also 50 degrees.

Front

If angle 3 is 70 degrees, what is the measure of angle 6 if they are alternate interior angles?

Back

Angle 6 is also 70 degrees.

Front

If angle 7 is 120 degrees, what is the measure of angle 8 if they are alternate exterior angles?

Back

Angle 8 is also 120 degrees.
