## Answer

Answer: (b) DF = 5 cm, ∠E = 60°

Two triangles are congruent if their corresponding sides are equal in length and their corresponding angles are equal in size.

In the first option, DF = 5 cm but ∠F is not equal to 60°.

In the third and the fourth options, the length of DE ≠ 5cm, since it is not defined.

In the second option, DF = 5cm and ∠E = 60° is satisfied.
