1.Sum of 2 sides is greater than the third side.

2.Difference between 2 sides is less than the third side.

This property holds for all the triangle except Isosceles triangle.Is it correct?

Why do you think it doesnt hold for isoceles?

For any triangle, Sum of 2 sides is greather than 3rd side.

a, b,c are sides

a+b>c
take b to opposite side.
c-b<a

So difference of two sides is less than third side.
