Question

Triangle ABC is congruent to triangle DEF .

Which statement must be true about the triangles?

m∠A=m∠E

AB = DE

AB = EF

m∠B=m∠D

Answer 1

I don't know if this is true because I've never really learned about this. but I think the answer is AB=DE

Answer 2

Answer: AB = DE

Explanation:

Given : Triangle ABC is congruent to triangle DEF .

We know that if two triangles are congruent then their corresponding sides and angles are congruent.

This property of congruent triangles are also known as CPCTC (corresponding parts of congruent triangles are congruent.)

Therefore,

m∠A=m∠D

m∠B=m∠E

m∠C=m∠F

AB=DE

BC=EF

AC=DF

From the given options the only right option is "AB = DE".
