What is a transversal?

Back

A transversal is a line that passes through two or more parallel lines, creating angles with those lines.

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 is the relationship between same-side interior angles when two parallel lines are cut by a transversal?

Back

Same-side interior angles are supplementary, meaning they add up to 180 degrees.
