1.  List the Congruent sides and angles:

2. Unit Essential Question: How do you use given information to construct a proof involving congruent triangles?

3. Essential Question: When are triangles congruent?

4.  Congruent Figures have the same size & shape. They can be transformed so that one will fit EXACTLY on the other:  Congruent figures have congruent corresponding parts.

5.  If these triangles are congruent, then list the congruent corresponding parts:  Two triangles are congruent if all three pairs of sides and all three pairs of angles are congruent.

7.  Statements Reasons

10.  What does it mean to be SUFFICIENT?  Would having 3 pairs of congruent Angles be sufficient to GUARANTEE two triangles are congruent?  Why or Why not?

11. Essential Question: What are the sufficient conditions to prove triangles are congruent?

15.  INCLUDED?!?!

20. Essential Question: What are the sufficient conditions to prove triangles are congruent?

21.  Included side!!!

28. Essential Question: How can you use congruent triangles to prove corresponding parts are congruent?

29.  Once you know that a pair of triangles are congruent, you can safely concluded that ALL of the corresponding parts of these triangles must also be congruent:  Corresponding Parts of Congruent Triangles are Congruent, or CPCTC.

34. Essential Questions: What does CPCTC reveal about Isosceles & Equilateral triangles?

35.  Base  Legs  Vertex Angle  Base Angles

42.  What is the definition of congruent triangles?  What are sufficient conditions to prove triangles congruent?  How do you use CPCTC?

43. Essential Question: What are the sufficient conditions to prove triangles are congruent?

44.  Hypotenuse  Legs

46.  Why isn’t it covered by SAS?  Need:  Two Right Triangles  Congruent Hypotenuses  Congruent Legs

50. Essential Question: How can you use congruent triangles to prove corresponding parts are congruent?
