Chapter 4 Congruent Triangles

Chapter 4 Congruent Triangles4-1 Congruent FiguresObjectivesStudents will be able to:Recognize congruent figures and their corresponding partsDefine and apply the third angles theoremUse congruent parts to prove triangles congruentEssential UnderstandingYou can determine whether two figures are congruent by comparing their corresponding parts.Congruent FiguresWhat do you know about congruent figures?Does the orientation of congruent figures matter?No, the congruent figures can be slid, flipped, or turned and they will still be congruentCongruent FiguresCongruent Polygons:Have congruent corresponding parts (equal sides and angles)When naming congruent figures, you must list corresponding parts (angles/vertices) in the same order
