What is a transversal?

Back

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

Front

What are corresponding angles?

Back

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

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 lines.

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

Back

Consecutive interior angles are supplementary, meaning they add up to 180 degrees.

What is the relationship between angle w and angle 3 if they are corresponding angles?

Back

If angle w measures 155 degrees, then angle 3 also measures 155 degrees.
