HW: 4.1 Exterior-angle-theorem

__Thurs Oct 10/20__

### Bell work 11

Handed back Quizzes. Questions over HW--Ext Angle Thm Sec 4.1

### Worked through two proofs--Triangle Sum Thm and Exterior Angle Thm

Completed the **Triangle Congruence "Sandwich Activity"** Explored the 4 Triangle Congruence Theorems ( 2 were not)

Began discussion of proof and reasoning proving triangles congruent:

HW: no homework : )

__Tues Oct 25 __

Bell Work 12 10/21/14

Continued discussion of proving triangles congruent using Triangle Congruence Postulates, SSS, SAS, ASA, & AAS from Sec 4-3 & Sec 4-4.

HW: Prac A Sec 4-3 & Sec 4-4 Prac A

Begin Triangle Congruence Proofs Packet C

If you have time, you could continue writing/typing out the Postulates and Theorems on pg 827--postulates through 21. And, Theorems pg 828 through 4.8. Simply add them to your list. If you have not started a list, you could start one. Also, familiarize yourself with all vocabulary from Sec 4.1--Sec 4.3 of your textbook.

__Thurs Oct 27__

Bell work 13

Continued to work with the Triangle Postulates & Triangle Congruence Proofs.

Geogebra Exploration

Explored why there is no AAA Congruence Postulate and no SSA.

Use congruent triangles (CPCTC--Corresponding Parts of Congruent Triangles are Congruent) to prove two triangles congruent from Sec 4-5.

Kahoot--SSS, SAS, ASA, AAS

HW: Finish proof packet C. Also, be working on proof packet D.

Sec 4.5 Proofs Packet D CPCTC finish as many as you can. Bring your questions in to class.

__Mon 10/31__

Quick Quiz

Discussed Sec 4-6--using properties of isosceles and equilateral triangles.

HW:

Review for Chapter 4

Heads up...Ch 4 Test will be Friday 11/4. Begin reviewing now.

Some things to help you be "Quiz Ready" :

Read p. 251--Chapter Summary and look over Chapter Review, pg 252-254.

Continue writing out the postulates and theorems from this chapter--can use them as references on the quiz. See p. 827-828 for the list. From the postulates, you should add #19-21. From the theorems, you should add 4.1-4.8.

Spend time on Khan Academy--topics under Triangles from the 2nd quarter grid Khan Grid 2nd qtr .

Go back and review assigned homework. Review your handout notes--don't forget our "investigation notes--sloppy notes" of exploring different triangles.
