This triangle is impossible to make.

Explanation:

Any triangle has a property that the sum of its any two sides is always greater than or equal to the third side.

Here let a,b,c denote the sides with a=14, b=9 and c=2.

I will now find the sum of any two sides and will check that is the property satisfied.

a+b=14+9=23

This is greater than c which is the third side.

a+c=14+2=16

This is also greater than b which is the third side.

b+c=9+2=11

This is less than a which is the third side.

So the property for the given lengths is not satisfied therefore the given triangle can not be formed.
