Question

it is given the triangle ABC = traingle FDE and AB =4cm , angle B = 40 degree and angle E = 60 degree, then which of the following is true.​

Answer 1

GIVEN:- ABC≅FDE

and AB= 4cm ,angle B= 40°,angle E=60°.

ANSWER:-(a) DE = 4cm , angle A = 80°

Therefore , by the property of congruency AB= FD

BC= DE

And congruent angle are same.

Answer 2

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=

5

cm, since it is not defined.

In the second option,

DF=

5

cm and

∠E=

60

∘

is satisfied.
