Question

If $AB\mathit{=}DE\mathit{,}\mathit{}BC\mathit{=}EF$ and $AC\mathit{=}DF$ then $∆ABC\cong$ ______________.

Answer 1

Given that, $AB\mathit{=}DE\mathit{,}\mathit{}BC\mathit{=}EF$ and $AC\mathit{=}DF$

If three sides of a triangle are equal to three sides of another triangle, then both triangles are congruent.

Therefore, $∆ABC\cong ∆DEF$ .
