difference between alt interior angles and alt exterior angles

**Alternative interior angle**

When a line (called a transversal) intersects a pair of parallel lines alternative interior angles are fo he **Alternate Interior Angles Theorem **states that

When two parallel lines are cut by a transversal, the resulting alternate interior angles are congruent.

rmed. Alternate interior angles are equal to each other.

**Alternative exterior angle**

One way to remember alternate exterior angles is that they are the vertical angles of the alternate interior angles. Alternate exterior angles** **are equal to one another.

The **Alternate Exterior Angles Theorem **states that

When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent.
