What are vertical angles?
Congruent angles formed by two intersecting lines. These angles are located across from each other.
400
Alternate Exterior Angles
If two parallel lines are intersected by a transversal, these angles are located on the outside of the two parallel lines on opposite sides of the transversal.

What are Alternate Interior Angles?
When 2 parallel lines are both intersected by a transversal, these angles are inside the two parallel lines and on opposite sides of the transversal.
500
Same-side interior angles
Same side exterior angles
If two parallel lines are cut by a transversal, these angles are on the inside of the two parallel lines and on the same side of the transversal.
