Chapter 4 Section 4.1 Congruent FiguresObjectives: To recognize congruent figures and their corresponding parts
Congruent figures -> have the same size and shape. When two figures are congruent, you can move one so that it fits exactly on the other one.
Congruent polygons -> have congruent corresponding parts (matching sides and angles). Matching vertices are corresponding vertices.
*When you name congruent polygons, always list corresponding vertices in the same order.*
Ex: List the congruent corresponding partsDTJFRCSides: TJ congruent to RC JD congruent to CFDT congruent to FR
Angles: T congruent to R J congruent to CD congruent to FThe fins of the Space Shuttle suggest congruent pentagons. Find m
