1. 1.6 Angles Warm-up (IN) Learning Objective: to name and measure anglesand to use them in various real-world situations Use the diagram: 1.Name all the rays that have the given endpoint. a.P b. Ac. X d. Y 2. Name two rays that contain each segment A Z I J H X P Y

2. Notes 2 rays with a common endpoint or Angles - Vertex must be middle letter or A B C 1 Congruent Angles - Q P R

3. X W Y Z Angle Addition Postulate – Ex 1 – B A D C 30º 150º CKC p. 37

4. Ex 2 – Q P R S 125º P, Q and R are collinear Ex 3 – R A T 1 2 3

5. HW – p. 37-39 #1-9 odd,11-18,26-28,31-33 Out – explain what the angle addition postulate is. Summary – Today’s lesson was… POW!!
