Ex 7.1 Class 7 Maths Question 3.
If ∆ABC ≅ ∆FED under the correspondence ABC ⟷ FED, write all the corresponding congruent parts of the triangles.
Solution:
Given: ∆ABC = ∆FED
and ABC ⟷ FED
∴ (begin{array}{l}{overline{mathrm{AB}} leftrightarrow overline{mathrm{FE}}, overline{mathrm{BC}} leftrightarrow overline{mathrm{ED}}, overline{mathrm{AC}} leftrightarrow overline{mathrm{FD}}} {angle mathrm{A} leftrightarrow angle mathrm{F}, angle mathrm{B} leftrightarrow angle mathrm{E}, angle mathrm{C} leftrightarrow angle mathrm{D}}end{array})
