5.2 Congruent Polygons OBJ: Students will be able to identify and use corresponding parts and use the Third Angles Theorem. Do Now- Solve for the missing Value 2x+3 75 55 93 5x 4x+6 Definitions Corresponding Part: Maps each part of a triangle to another triangle. Corresponding Sides: sides of different polygons that are congruent. Corresponding Angles: angles of different polygons that are congruent. Example 1 Example 2 Example 3 Properties of Triangle Congruence Reflexive: Symmetric: Transitive: Third Angle Theorem If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent. Example 4 Example 5 HW Pg. 243 3-10,13-14
