1 Welcome Back! Warm-Up… Quickwrite…
Write everything you know about each triangle Quickwrite… Describe one relaxing thing and one productive thing you did during winter break. Which was more memorable? Why? Ex: “One relaxing thing I did was __________ and one productive thing I did was __________. I think __________ was more memorable because _____________________.”

2 Compare and Explain… your Warm-Up starting with Student #1 (1 min)
Write everything you know about each triangle

3 Round Robin… starting with the student wearing the warmest clothes at your table (1 min) Describe one relaxing thing and one productive thing you did during winter break. Which was more memorable? Why? Ex: “One relaxing thing I did was __________ and one productive thing I did was __________. I think __________ was more memorable because _____________________.”

4 Angles of Triangles

5 Where do we see triangles in real life?

6 What do we know about the angles?
How can we classify this triangle by its sides AND angles?

7 Angle Measures of Triangles
What do know about any of these angle measures?

8 Theorems

9 Example Find the m∠JKM

10 What is a Corollary? A corollary to a theorem is a statement that can be proved easily using the theorem
