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 angles that are in the same position on two parallel lines cut by a transversal.

What are alternate interior angles?

Back

Alternate interior angles are angles that are on opposite sides of the transversal and inside the two parallel lines.

What is the relationship between interior angles on the same side of the transversal?

Back

Interior angles on the same side of the transversal are supplementary, meaning they add up to 180 degrees.
