44, 45 Congruence Postulates SSS Postulate (SideSideSide) If the 3 sides of one triangle are congruent to the 3 sides of another triangle, then the triangles are congruent. 1 SAS (SideAngleSide) If 2 sides and the included angle of one triangle are congruent to 2 sides and the included angle of another triangle, then the triangles are congruent. 2 ASA (AngleSideAngle) If 2 angles and the included side of one triangle are congruent to 2 angles and the included side of another triangle, then the triangles are congruent. 3 AAS (AngleAngleSide) If 2 angles and a nonincluded side of one triangle are congruent to the corresponding 2 angles and nonincluded side of another triangle, then the triangles are congruent. 4
