Question

state whether the following triangles are conguruent or not ? give reason for your answer ​

Answer 1

Answer:

Following triangles are congruent.

Step-by-step explanation:

BC = FE

<C = <F

From ABC,

<A + <B +<C = 180°

<A + 50° +70° =180°

<A =60°

And from DEF,

<D + <E + <F =180°

60° +<E + 70° =180°

<E = 50°

All the angles are same.

That's why these triangles are congruent by SSS.
