4-5 Using Congruent Triangles


 * Summary: **

This section will teach you how to use congruent triangle to plan and write proofs. You will learn to use congruent triangles to prove that all Corresponding Parts of Congruent Triangles are Congruent by using CPCTC. The textbook section that covers this topic is section 4.5.

__ CPCTC: __ Corresponding Parts of Congruent Triangles are Congruent
 * Vocabulary/ Theorems: **


 * Rules when Using Congruent Triangles: **
 * After proving that a triangle is congruent by SSS, SAS, AAS, ASA or HL theorem, you can prove that the any of the corresponding parts of the congruent triangles because of the theorem CPCTC.
 * When writing either paragraph or two-column proofs mark the diagram with the given information then finish marking the diagram with deduced information.
