Step 1
Given
[tex]\Delta ABC\cong\Delta DEF[/tex]
Required:
[tex]To\text{ find which of the option is not a true statement}[/tex]
Step 2
Congruent triangles have the same shape and size. The length of the corresponding sides of congruent triangles and the size of corresponding angles are equal.
Step 3
Find the statement that is not true.
[tex]\begin{gathered} \text{Option A } \\ AC\cong DF\text{ }---\text{ is true} \end{gathered}[/tex][tex]\begin{gathered} \text{Option B} \\ \angle B\cong\angle E---\text{ is true} \end{gathered}[/tex][tex]\begin{gathered} \text{Option C} \\ FE\cong BA---\text{ is not true} \\ \text{Option D} \\ \angle F\cong\angle C-----is\text{ true} \\ \end{gathered}[/tex]
Hence, the answer is option C
