Grab a ruler and try drawing the triangles. Or grab some straws and cut them to appropriate lengths. What do you see?

The sum of any two sides of a triangle must be greater than the thrid side.
I think you can figure out which are triangles or not.

or...(using integers) given a and b as 2 sides of a triangle,
then 3rd side c = |a-b|+1 to a+b-1

|a-b|+1 ?
Yes: you can have an isosceles triangle with equal sides = 10^(googleplex!) and base = 1.
