Answer:
[tex]\boxed{m\angle A = m\angle D}\\[/tex]
Step-by-step explanation:
When you use a congruence statement, you must line up the corresponding parts of the triangles.
BC = DE is wrong, because BC = EF.
[tex]\boxed{m \angle A = m \angle D}[/tex] is correct.
m∠B = m∠F is wrong, because m∠B = m∠E.
AC = EF is wrong, because AC = DF

Triangle ABC is congruent to triangle DEF.m∠A=m∠D must be true about the triangles. Option B is correct.
What is the triangle?
A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.
Triangle DEF and triangle ABC are congruent. The following assertion concerning triangles must be true:
m∠A=m∠D
Hence, statement B is correct.
