If the following pair of the triangle is congruent? state the condition of congruency :
In ΔABC and ΔDEF, ∠B = ∠E = 90o; AC = DF and BC = EF.

उत्तर
In Δ ABC and Δ DEF
∠B = ∠E = 90ο
Hyp. AC= HYp. DF
BC = EF
By Right Angel- Hypotenuse-Side Criterion of congruency, the triangles
Δ ABC and Δ DEF are congruent to each other.
∴ Δ ABC ≅ Δ DEF
