It is given that ∆ ABC ≅ ∆ FDE, AB = 7 cm, ∠ B = 40° and ∠ A = 75°. Then which of the following is true?
DE = 7 cm, ∠ D = 40°
FD = 7 cm, ∠ F = 65°
FD = 7 cm, ∠E = 65°
DE = 7 cm, ∠ E = 65

Step-by-step explanation:
Correct option is
B
DF=5cm,∠E=60
0
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.
