You don't really know anything about the triangle, so there are a number of choices. Side c has to be less than a + b. So you could write c < a + b. As far as possible values of c, it could be anything smaller than a + b, so even a + b - .0001 is a possible value (it would look like a totally squashed triangle. There is an interactive one here http://www.mathsisfun.com/geometry/triangles-interactive.html that you can play with.
