Question 3.
If ∆ ABC ≅ ∆ FED under the correspondence ABC ⟷ FED, write all the corresponding congruent parts of the triangles.

Solution:
The ∆ ABC ≅ ∆ FED then the corresponding vertices A and F, B and E, C and D. The corresponding sides are $\overline{\mathrm{AB}}$ and FE, BC and ED, CA, and DF. The corresponding angles are ∠A and ∠F, ∠B and ∠E, and ∠C and ∠D.

Solution:

i) ∠E
∠E ≅ ∠C,

ii) $$\overline{\mathbf{E} \mathbf{F}}$$
$$\overline{\mathbf{E} \mathbf{F}}$$ ≅ $$\overline{\mathbf{C} \mathbf{A}}$$

iii) ∠F
∠F ≅ ∠A

iv) $$\overline{\mathbf{D F}}$$
$$\overline{\mathbf{D F}}$$ ≅ $$\overline{\mathbf{B A}}$$
