Congruency of Triangles

If Δ ABC is congruent to Δ DEF and if AB = 3 = DE and BC = EF = 4 , then necessary condition is

• ∠ A = ∠ D

• ∠ B = ∠E

• ∠ C = ∠ F

• CA = FD

The three sides of one triangle are equal to the three corresponding sides of another triangle then the triangle is congruent by ———- criteria.
