thanks you ^_^!!!!!!!!!!

có nhiều trường hợp lắm, nên mik làm 2 cáh thui nha:

Cách 1: trường hợp cạnh - cạnh - cạnh

Ta có:    AB = DE

              BC = EF

vậy cần: AC = DF

Cách 2: trường hợp cạnh - góc - cạnh

 Ta có:    AB = DE

               BC = EF

Vậy cần \(\widehat{ABC}=\widehat{DEF}\)

hok tốt!!

để tam giác ABC= tam giác DEF theo trường hợp c-c-c thì ta cần thêm điều kiện AC=DF

...............................................................................c-g-c..........................................góc A = góc D

Chúc bạn học tốt
