prove that the difference of any two sides of a triangle is less than third side.

Let ABC be a triangle having sides AB, BC and CA.

We know that the sum of any two sides of a triangle is greater than the third side.

∴ AB + BC > CA

⇒AB > CA – BC

This shows that difference of two sides is less than the third side of the triangle.

Similarly, we can prove it for other sides as well.
