Bunuel Statement 2 says AB=2BC. Lets say BC=x then, AB=2x.

Thus, the third side has to be less than x and greater than 3x. So the triangle can't be isosceles.

Please clarify...

Hi NehaBhargava

If BC = x and AB = 2x, the third side has to be LESS than 3x (the sum of two sides is greater than the 3rd side in a triangle)

The third side can still be equal to 2x, so this statement is not sufficient.

Hope this clears your doubt.
