Solution

We know the sum of the length of any two sides of the triangle is always greater than the length of the third side.

Given the length of the sides is 5cm,4cm&9cm.

Here 5+9>4

9+4>5

But, 5+4=9, does not follows the criteria to form a triangle.

Since any of the above cases does not fulfill the criteria of forming a triangle.

Therefore, it is not possible to form a triangle with given set of sides.
