The triangles to the right are congruent. Which of the following statements must be true

The true statement is one that derives from the condition that ΔABC and
ΔDEF are congruent.
Response:
Given that the tringles are congruent, we have;
The length of the corresponding sides are equal
Similarly, the measure of the corresponding are equal
The side [tex]\mathbf{\overline{AC}}[/tex] ≅ Side [tex]\overline{DE}[/tex]
Side [tex]\mathbf{\overline{AB}}[/tex] ≅ Side [tex]\overline{EF}[/tex]
Which gives;
∠A ≅ ∠D
Given that ΔABC ≅ ΔDEF, we have;
Side [tex]\mathbf{\overline{BC}}[/tex] ≅ Side [tex]\overline{DF}[/tex]
Which gives;
∠C ≅ ∠F
Therefore;
∠B ≅ ∠D
