Question

1. If ∆ABC and ∆DEF are congruent under the correspondence ABC <––>FED, write all the corresponding congruent parts of the triangles.​

Answer 1

If ∆ ABC ≅ ∆ FED under the correspondence ABC ⟷ FED, all the corresponding congruent parts of the triangles are corresponding congruent angles: ∠A ⟷ ∠F, ∠B ⟷ ∠E, and ∠C ⟷ ∠D and corresponding sides: AB ⟷ FE, BC ⟷ ED, and AC ⟷ FD.
