If δabc ≅ δfde, which of the following statements is true?
a) ∠a ≅ ∠e
b) ∠b ≅ ∠f
c) ∠a ≅ ∠d
d) ∠b ≅ ∠d

Option D) ∠B ≅ ∠D

Step-by-step explanation:

we know that

If two triangles are congruent, then the corresponding sides and the corresponding angles are congruent

so

If ΔABC ≅ ΔFDE

the corresponding angles are

∠A and ∠F

∠B and ∠D

∠C and ∠E

so

∠A ≅ ∠F

∠B ≅ ∠D

∠C ≅ ∠E

therefore

The statement that is true is ∠B ≅ ∠D
