  1. Angle Pairs 1.5

  2. Solutions to HW • 1. 89, 45, 44 • 2. -14 • 3. 19 • 4. 32 • 5. 13 • 6 23, 25

  3. Solutions to HW • 1. Interior 8. Angle Addition • 2. Exterior 9. Congruent Marks • 3. 39 or 40, Acute • 4. 130 or 131, Obtuse • 5. Straight • 6. 25, 25, Congruent • 7. 90, right

  4. Vocabulary

  5. Examples • Where are supplementary angles? • What is the degree of <AFB • What is the degree of <CFD

  6. What can we conclude from this diagram? Ex: <1 = <2

  7. Linear Pair • A linear pair is a pair of adjacent angles whose noncommon sides are opposite rays. The angles of a linear pair form a straight angle. • What will be the total degree when you add both angles <ABD and <DBC?

  8. Algebra Example • Solve for x given this linear pair
