$(ii).\ \overline{EF}$
$(iii).\ \angle F$
$(iv).\ \overline{DF}$

Given: $∆DEF ≅ ∆BCA$.

To do: To write the part(s) of $∆BCA$ that correspond to

$(i).\ \angle E$ 

$(ii).\ \overline{EF}$ 

$(iii).\ \angle F$ 

$(iv).\ \overline{DF}$


Solution:

Given that $∆ DEF ≅ ∆ BCA$

Since we know that corresponding parts of congruent triangles are equal,  hence we can say that the corresponding sides and angles of both congruent triangles are equal.

$(i).\ ∠E=∠C$

$(ii)$. side $EF=$side $CA$

$(iii).\ ∠F=∠A$

$(iv).$ side $DF=$side $BA$
