  1. Angles 10/14/13

  2. Adjacent Angles • 2 angle’s that share a side • They are “neighbors” • Are <a and <b adjacent? a b b a a b a b

  3. Supplementary Angles • 2 or more angle’s that add up to 180o • The “SUPPer” table is flat! 110o 70o 160o 20o 40o 140o 91o 89o

  4. Supplementary Angles cont. 110o ? 50o ? 70o 60o 70o

  5. ComplementaryAngles • 2 or more angle’s that add up to 90o (right angle) • When I get a “Complement” I feel so RIGHT! 3o 87o 70o 45o 20o 45o

  6. ComplementaryAngles cont. ? 45o 70o ? 20o 45o

  7. Vertical Angles • 2 congruent ( ) angles formed by intersecting lines directly across from each other. (NOT ADJACENT)

  8. 160o ? 20o 20o ? 160o

  9. 120o x 60o 60o x 120o

  10. 65o x 115o 115o x 65o

  11. Naming Angles • The vertex (corner) of the angle is always the middle letter. A B C D E

  12. Practice • Name this angle. • Name SUPPLEMENTARY angles to HMK • Name two VERTICAL angles. • If the m HMK = 35o… • A) what is the m RMK? • B) what is the m PMR? • C) what is the m PMH? H K M P R

  13. Begin Worksheet • Use your given notes to help you answer the questions on the worksheet. • Whatever you do not complete in class needs to be completed for homework. This will count as a 20 point CLASSWORK grade to be turned in to your teacher! • Don’t forget your homework in the textbook page 711 # 1-7 as well!!!!

  14. Angles in Parallel Lines 10/15/13

  15. Angles in Parallel Lines Practice What are < 5 & < 1? What are < 1 & < 4? What are < 3 & < 5? What are < 2 & < 8? What are < 6 & < 8? What are < 1 & < 3? What are < 1 & < 2? What are < 1 & < 7? What are < 4 & < 6? Supplementary Vertical Corresponding Corresponding Alternate Interior Vertical Alternate Exterior Supplementary Alternate Exterior 40o 1 2 4 3 7 6 8 5 If m<2 = 40o, then…. WHY???
