Question
In two triangles ABC and DEF, it is given that $\angle\text{A}=\angle\text{D},\angle\text{B}=\angle\text{E}$ and $\angle\text{C}=\angle\text{F},$ Are the two triangles necessarily congruent?

Answer
It is given that $\angle\text{A}=\angle\text{D},\angle\text{B}=\angle\text{E},\angle\text{C}=\angle\text{F}$
For necessarily trialnge to be congruent, sides also be equal.
For necessarily trialnge to be congruent, sides also be equal.
