What is a transversal?

Back

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

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 lines.

What is the relationship between consecutive interior angles when the lines are parallel?

Back

When the lines are parallel, consecutive interior angles are supplementary (they add up to 180 degrees).
