What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal.

Front

What is the relationship between angles formed by two parallel lines cut by a transversal?

Back

The angles formed have specific relationships: corresponding angles are equal, alternate interior angles are equal, and same-side interior angles are supplementary.
