Answer:
Three main types of angles are formed by parallel lines and a transversal line. The angles formed by parallel lines and a transversal lines are either equal or complementary. They are all related in a way that can all be solved.
Co-interior: "C" shape: angles add to 90°
Alternating: "Z" shape: angles are the same
Corresponding: "F" shape: angles are the same
