## Vocabulary

**corresponding angles - When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles.**

**alternate exterior angles- The ****pairs of angles** on opposite sides of the transversal but outside the two line**Same Side Interior Angles - are two angles that are on the same sideof the transversal and on the interior of the two lines.****same side exterior angles- When a transversal intersects two lines, the two lines are parallel if and only if interior angles on the same side of the transversal and exterior angles on the same side of the transversal are supplementary**
