To prove triangles congruent by SAS (Side-Angle-Side), we must know that two sides and the included angle of one triangle are congruent to the corresponding two sides and included angle of the other triangle.
Therefore, to prove triangles congruent by SAS, we must know the lengths of two sides of one triangle, the measure of the included angle, and the corresponding lengths of the two sides of the other triangle.
