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.

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

Discussed Sec 4-6--using properties of isosceles and equilateral triangles.
p. 239 #8-25 Classwork--notes
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.
Proof Packet D in today
HW: Work on Review for Chapter 4
Unit 4 Test--Triangle Congruence

- go to my Google Classroom and Complete the Geogebra Exploration of Sec 5.1 and Sec 5.2
Start on HW, p. 267 & do #1-13.
Congruent Triangles (Geometry Curriculum - Unit 4)
This bundle contains notes, homework assignments, three quizzes, a study guide and a unit test that cover the following topics:
• Classifying Triangles by Sides and Angles
• Angles of Triangles: Triangle Angle Sum Theorem and Exterior Angle Theorem
• Isosceles and Equilateral Triangles
• Triangle Congruence: SSS and SAS
• Triangle Congruence: ASA and AAS
• Right Triangle Congruence: HL
• Mixed Review of Triangle Congruence
• Corresponding Parts of Congruent Triangles are Congruent (CPCTC)
Please download the preview to see a sample outline along with a collage of some of the pages.
NEW: Assessments are now EDITABLE! Now you can easily make multiple versions or customize to fit your needs! PowerPoint and Equation Editor (usually built in to PowerPoint) are required to edit these files. There is a folder titled "Editable Assessments" when you download. This is where you will find editable versions of each quiz and the unit test. If your Equation Editor is incompatible with mine, simply delete my equation and insert your own.
