Congruent Triangles Review Honors Geometry CCHS Which rule proves the triangles congruent? ASA What rule proves the triangles congruent? SAS What rule proves the triangles congruent? Not enough information (SSA labeling) What rule proves the triangles congruent? Given: π¨π© β π©πͺ π©π« πππππππ < π¨π©πͺ SAS What rule proves the triangles congruent? Not enough information (AAS labeling) What rule proves the triangles congruent? Given: < πΎ β < π² πΎπ½ β π½π² ASA One Step Proof: Given: < πππ β < πππ < πππ β < πππ Prove: < πππ β < πππ Subtraction Property One Step Proof Given: <1 comp. <4 <2 comp. <3 < π β < π Prove: < 3 β < 4 If angles are complementary to congruent angles, then they are congruent One Step Proof Given: ππ β ππ Prove: WX β YZ Subtraction Property One Step Proof: Given: π·π β ππΉ M and N are mdpts Prove: DG β FG Multiplication Property Chapter 3 Tips ο Labeling Congruent Triangles: Follow around the perimeter of a labeled triangle ο Review Properties (sec. 2.4-2.7 in book) ο Proofs: LABEL DIAGRAMS!!! ο Proofs: Include all labeling steps in proof ο Triangle Congruence Proofs: Make sure you have THREE CONGRUENCE statements! (Label S and A) ο Proofs: Make sure you have satisfied requirements of IF statements before including a step.
