4-2 Triangle Congruence (SSS & SAS)
DODEA STANDARD
G.1.1: Demonstrate understanding by identifying and giving examples of undefined terms, axioms, theorems, and inductive and deductive reasoning;
G.2.1: Identify necessary and sufficient conditions for congruence and similarity in triangles, and use these conditions in proofs;G.6.3: Use properties of congruent and similar triangles, quadrilaterals, and other polygons to solve problems;
G.6.4: Prove and use theorems involving the properties of parallel lines cut by a transversal, similarity, congruence, triangles, quadrilaterals, and circles;
OBJECTIVE
To prove two triangles congruent using the SSS and SAS Postulates
