10 Wednesday 1. Finish the Chapter 2 of the Journey 10.1 Congruence 1. Peruse the Utah Core to read the description of school geometry. 2. Read geometry sections for grade 7 and 8 then congruence sections in high school standards. 3. Deļ¬nition of congruence: Triangles ABC and A B C are congruent if and only if there is an isometry f : R2 → R2 such that f (A) = A , f (B) = B and f (C) = C . 4. Prove SSS: Triangles ABC and A B C are congruent if and only if the corresponding sides have equal lengths. 5. Prove SAS: Triangles ABC and A B C are congruent if and only if two corresponding sides have equal lengths and the angles they determine have equal measures. 6. Prove ASA: Triangles ABC and A B C are congruent if and only if two corresponding angles have equal measuers and the side they share have equal lengths. 13
