4.6- CPCTC

Today we discussed how to apply CPCTC which stands for Corresponding Parts of Congruent Triangles are Congruent.  Once you have proven that two triangles are congruent, the corresponding parts must also be congruent.  We also went over the chapter 4 terms you must have for your study project, which is due on Friday.

The Chapter 4 Study Project terms are:

Triangle Sum Theorem

Exterior Angle Theorem

Third Angles Theorem

SSS Congruence Postulate

SAS Congruence Postulate

HL Congruence Theorem

ASA Congruence Postulate

AAS Congruence Theorem

CPCTC

Base Angles Theorem

Converse of Base Angles Theorem

Tonight's homework is P. 259-261 #11,14,23,26,31.  Please remember that your Chapter 4 QUIZ is on Friday and the corresponding study project is due that day also.
