Congruent Triangles ◦ Each triangle has six parts: three angles and three sides ◦ If the corresponding six parts of one triangle are congruent to the six parts of another triangle, then the triangles are congruent CPCTC (corresponding parts of congruent triangles are congruent) ◦ Orientation of the triangles is not important. Flip, slide, turn, etc……if the corresponding parts are congruent, the triangles are congruent

1. Given:  ABC   RQC. Name all the corresponding parts. Congruent Sides:Congruent Angles: 2. **The order matters! Is  ABC   DEF equivalent to  ABC   FED?
