Proofs The following triangle congruent postulates guarantee that 2 triangles are congruent 2 angles and the side between the angles are congruent Angle-side –angle (ASA)

Side-angle-side (SAS) Two sides and an angle between the sides are congruent

3 sides of the triangle are congruent Side-side-side (SSS) 3 sides of the triangle are congruent Two angles and the side not between the angles Angle-angle-side (AAS)

Does not prove triangle congruence Angle-angle-angle (AAA) 3 angles are congruent Both triangles have 60 degree <‘s but the side lengths are all different

2 sides and the angle not between them Side-side-angle (SSA)
