  1. S R T Q Aim: How can we identify angle pairs? HW#7 p40/15-34, 44, 50-54, 56 Do-Now: 1) If EG= 49, EF = 2x+ 3, and FG = 4x - 2, Find EF. 2) If m RQS = 2x - 1 and m SQT = x, find m RQS

  2. Types of angle pair 1)Vertical angles two angles whose sides are opposite rays 2)Adjacent angles 3 4 1 2 two angles with a common side,a common vertex.

  3. 2 1 3)Complementary angles 40 B 50 A two angles whose measures have sum 90. Each angle is called the complement of the other 4)Supplementary angles 3 4 two angles whose measures have sum 180 Each angle is called the supplement of the other

  4. 2 1 3 5 4 Ex1) In the diagram identify pairs of numbered angles that are related as follows: a. complementary b. supplementary c. vertical d. Name two pairs of adjacent angles

  5. 3 2 4 1 5 What can you conclude from the information in the diagram?

  6. Ex2) Can you make each conclusion from the information in the diagram? Explain. (symbol in a and b is congruent) a. TW WV b. PW WQ C. TV PQ d. TV bisects PQ e. W is the midpoint of TV. ≅ T ≅ Q W P V f. PQ bisects TV.
