6.2 & 6.3 - Triangle Congruence by SSS, SAS, Postulate or Theorem You need ASA, and AAS Side-Side-Side (SSS) three sides Side-Angle-Side (SAS) two sides and an included angle Recap: You can prove triangles congruent Angle-Side-Angle (ASA) two angles and an included side with limited information about their Angle-Angle-Side (AAS) two angles and a nonincluded side congruent sides and angles. Examples: Which postulate or theorem, if any, could you use to prove the two triangles congruent? If there is not enough information to prove the triangles congruent, write not enough information. 2. 4. 3. W 5.. 6.4 - Using Corresponding Parts of Congruent Triangles Recap: Once you know that triangles are congruent, you can make conclusions about corresponding sides and angles because, by definition, corresponding parts of congruent triangles are congruent. You can use congruent triangles in the proofs of many theorems. Examples: How can you use congruent triangles to prove the statement true? W 6. LQ=LD 7. TV= YW W K K D T Y X O E VRecap: Congruent polygons have congruent corresponding parts. When you name congruent polygons, always list corresponding vertices in the same order. Examples: 1. RSTUV=KLMNO. Complete the congruence statements a. TS= b. ZN=. C. LM
