Parallel Lines Cut by a Transversal Test

Front

What is a transversal?

Back

A transversal is a line that intersects two or more other lines at distinct points.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal.

Front

What are same side interior angles?

Back

Same side interior angles are pairs of angles that lie between two lines and on the same side of a transversal.

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 same side interior angles when two parallel lines are cut by a transversal?

Back

Same side interior angles are supplementary (add up to 180 degrees).

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

If angle 1 = 27°, what is the measure of angle 2 if they are corresponding angles?

Back

Angle 2 = 27°.

Front

If angle 1 = 49°, what is the measure of angle 3 if they are vertical angles?

Back

Angle 3 = 49°.
