Congruent Triangles
Lesson 4-3 OBJECTIVE:
SWBAT name and label corresponding parts of congruent triangles and identify congruence transformations. Corresponding Parts of Congruent Triangles are Congruent (CPCTC) - Triangles
that are the same size and shape are congruent triangles. Each triangle has three
angles and three sides. If all six of the corresponding parts of the two triangles are
congruent, then the triangles are congruent. 1. Δ
