Worksheet on Proofs due Thursday/Friday (Aligns to CO-B8a)
Assessment on triangle congruence and transformations next class
Resources:
video example very similar to homework problems: https://www.youtube.com/watch?v=ALXsm9jlQCg
Tuesday/Wednesday
Estimation warm up, then review of basic triangle congruence shortcuts. Took assessment on transformations and triangle congruence. Worked through example of SSS on the coordinate plane. Talked about HL, and proved the Triangle Angle Sum theorem. (Sub was present Wednesday). Notes from the board
Homework: finish hw assigned Monday

Thursday/Friday
Clicker activity going over similar skills as assessment. Went over homework some before turning it in. Did some review problems (p. 165: 7, 9, 10) and then learned what CPCTC was through an analogy involving car parts. Then used HL from Tuesday and CPCTC from today to develop a new theorem about isosceles triangles. (p. 186). Finally, studied the exterior angle theorem (and proved it) (p. 183). Notes from board
Homework: p. 189: #1-19 (odd) (CO-C10a)
