Chapter 4.6 Notes: Use Congruent Triangles Goal: You will use congruent triangles to prove that corresponding parts are congruent.

2
Properties of Congruent Triangles A D B C E F What pairs of angles and sides are congruent? __________________________________________ __________________________________________

3
Using CPCTC: Once you know that triangles are congruent, you can make conclusions about corresponding sides and angles because Corresponding Parts of Congruent Triangles are Congruent (CPCTC). Ex.1: Suppose you know that by SAS. Which additional pairs of sides and angles are congruent by CPCTC? A B 1 2 D 4 C
