Question

4 cm.
It is given the AABC=AFDE and AB= 4 cm, B = 40° and ZE= 60°,
then which of the following is true.
(A) DE = 4 cm, ZA=80°
(B) DE = 4 cm, ZC=80°
(C) DF = 4 cm, ZA=80°
(D) DF = 4 cm, ZC=80°​

Answer 1

Step-by-step explanation:

ANSWER

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.
