Suppose the sides are a, b, and 6.  Then




By the three triangular inequalities:

, , 

Since , 

Substituting in the three triangular inequalities:

, , 

, , 


From  we have 

     , or , and since a is an integer,

     {a>=2}}}

So 2 is the smallest integer a can be.  

From , we can also similarly show that 7 is the largest
integer a can be.


We could have interchanged a and b and shown the same for b, so

the smallest integer either of the sides other than the side that is 6
coul dbe is 2.
