Answer:

SAS

Step-by-step explanation:

Consider triangles ABC and DEF. In these triangles,

  • AC ≅ FD;
  • AB ≅ DE;
  • ∠A ≅ ∠D (included angle).

Thus, by SAS postulate, triangles ABC and DEF are congruent.

The Side Angle Side postulate (SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
