  1. (4.1) Congruent Figures There’s no crying in baseball! -Jimmy

  2. Unit 4 Congruent Triangles ~ Standards4.1 Objects in the plane can be transformed, and those transformations can be described and analyzed algebraically.Prove geometric theorems (Lines, Angles, Triangles, Parallelograms)

  3. Unit 4 Congruent Triangles ~ Lesson Target:To recognize congruent figures and their corresponding parts.

  4. Congruent Figures Congruent Polygons: Congruent polygons are polygons that have corresponding sides that are congruent and corresponding angles that are congruent. Ex. Of corresponding: AX corresponds to PY AX PY XB YQ BC QR CA RP

  5. Congruent Figures To be congruent, figures must have the same: • Shape • Size • You can slide, flip or turn them so that one fits exactly over the other

  6. Congruent Figures Draw and List the congruent corresponding parts.

  7. Congruent Figures Given that the following pentagons are congruent, find the value of C A R W 132° B E 95° P S T D

  8. Congruent Figures Theorem 4-1: If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent. 92° 40°

  9. Congruent Figures Decide whether the triangles are congruent. Justify! E 3 4 B D 4 C 3 A
