If ∆ DEF ≅ ∆ BCA, write the part of ∆ BCA that correspond to
i) ∠E (ii) EF (iii) ∠F (iv) 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
