Question

hi, I have written 45 45 90 triangle instead of isosceles in the answer of the question given above. is it ok?​

Answer 1

I dont think

because you had to prove that......

Answer 2

Sorry mate it is wrong.

All 45-45-90° triangles are isosceles triangle but every isosceles triangle is not a 45-45-90°

So it's not necessary that the triangle in in the question is 45-45-90° it can also be an isosceles triangle with different angles.
