How do you know if it's an SSS postulate?

• if three sides of one triangle are congruent to the corresponding three sides of another triangle, then the triangles are congruent

• if two angles and any side (non-included) on one triangle are congruent to two angles and any side of another triangle, then the triangles are congruent
