Hi, please explain what I did wrong in this problem in part B

SOLUTION
The first has been aswered for you. So let's continue from the second part
(b) ASA means angle-side-angle theorem, so they want you to state which of angles of the two trianles in the first part are congruent by ASA.
Now angle BCA at angle A is congruent to angle DFE at angle F,
so the answer here is
[tex]\hat{\text{BCA}}\text{ }\cong\hat{DFE}[/tex](c) HL,
