Then which of the following is true?
a) DF = 5 cm, ∠F = 60°
b) DF = 5 cm, ∠E = 60°
c) DE = 5 cm, ∠E = 60°
d) DE = 5 cm, ∠D = 40°

Answer:
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.
