 Classifying Triangles Worksheet   --  Classifying Triangles Answers

  •  See  Notes for Sec 4-2--identifying congruent figures and corresponding parts.     see  Sec 4.2 Notes Ans   Also see your textbook, pg 202 for help.


 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.

Quick Quiz 

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.

 Unit 4 Test--Triangle Congruence



Ch 5, and READ Sec 5-1 p. 264-267  &    Choose 1 of the following:


  • Do pg Act 5.1 on pg 263 in your textbook.  Completing with a ruler and protractor by hand.  Compete questions #1-4.


  • 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.








Product Description

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.
