Class 9 Maths Ch 7 MCQ Question 11.
It is given that ΔABC = ΔFDE and AB = 5 cm, ∠B = 40° and ∠A = 80°. Then which of the following is true?
(а) DF = 5 cm, ∠F = 60°
(b) DF = 5 cm, ∠E = 60°
(c) DE = 5 cm, ∠E = 60°
(d) DE = 5 cm, ∠D = 40°

Answer

Answer: (b) DF = 5 cm, ∠E = 60°

Two triangles are congruent if their corresponding sides are equal in length and their corresponding angles are equal in size.
In the first option, DF = 5 cm but ∠F is not equal to 60°.
In the third and the fourth options, the length of DE ≠ 5cm, since it is not defined.
In the second option, DF = 5cm and ∠E = 60° is satisfied.
