    • The student will use the relationships between angles formed by two lines cut by a transversal to. a) determine whether two lines are parallel; b) verify the parallelism, using algebraic and coordinate methods as well as deductive proofs; and. c) solve real-world problems involving angles formed when parallel lines are cut by a transversal.
    • By Mark Ryan . Complementary angles are two angles that add up to 90°, or a right angle; two supplementary angles add up to 180°, or a straight angle. These angles aren’t the most exciting things in geometry, but you have to be able to spot them in a diagram and know how to use the related theorems in proofs.
    • Angle Pairs Vertical angles are pairs of congruent angles created when two lines intersect. Adjacent angles are two angles that have a common ray between them. Complementary angles are two angles that together can form a right angle. The sum of their measures is 908. Supplementary angles are two angles that together can form a straight angle.
