Congruence with proofs

2nd semester 5/6 class had talked about congruence with triangles. Congruence included statemnets with proofs. These prooves are statements that tell wether or not the triangles are equal in certain measurements. The final proofs concluded the triangles congruency. These statments are Side,side,side(sss): proofing all sides are the same. side,angle,side(sas):proofing a side then an angle then side. Angle,angle,side(aas,saa): proofing angle,angle, then a side. Angle,side,angle(asa): An angle then a side then a angle. Last Hypotynuse leg(HL): if the triangles are right the longest side(Hypotynuse).
