Question

Triangle ABC is congruent to triangle DEF .

Which statement must be true about the triangles?

BC = DE
AC = EF
m∠B=m∠F
m∠A=m∠D

Answer 1

The statement m∠A=m∠D is true

Answer 2

Explanation:

Alright lets get started.

Please refer the diagram I have attached.

For both triangles should be congruent, adjacent sides should be congruent or adjacent angles should be same.

BC = EF Which is not matching with our option.

AC = DF Which is not matching with our option.

angle B = angle E Which is not matching with our option.

angle A = angle D adjacent angle, whiich is matching with our option.

Hence angle A = angle D for both triangles should congruent. : Answer
