Parallel Cut by Transversal

Front

What are corresponding angles?

Back

Angles that are in the same position on parallel lines in relation to 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 parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

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

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the parallel lines. They are supplementary (add up to 180 degrees).

Front

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

Back

The angles formed have specific relationships: corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.

Front

If angle A is 70 degrees, what is the measure of angle C if A and C are corresponding angles?

Back

Angle C is also 70 degrees.

Front

If angle 6 is 25 degrees, what is the measure of angle 7 if they are consecutive interior angles?

Back

Angle 7 is 155 degrees.

Front

If angle 8 is 70 degrees, what is the measure of angle 2 if they are alternate interior angles?

Back

Angle 2 is also 70 degrees.

Front

If angle 1 is 135 degrees, what is the measure of angle 3 if they are corresponding angles?

Back

Angle 3 is also 135 degrees.

Front

What is the sum of the measures of angles A and G if they are supplementary?

Back

The sum is 180 degrees.
