Question about Green's Theorem

I am working on a take home quiz for my Calculus III class, and one of the problems says "Verify Green's Theorem for the line integral ∫xy dx + x² dy, where C is the triangle with vertices (0,0) (1,1) (2,0)."

Ok so this might be kind of a dumb question, but since it says "Verify" instead of "evaulate" am I supposed to do something different rather than find what the integral is equal to? I know how to evaluate this but I just am not sure if that means the same thing as verify. I don't want to misinterpret the problem and end getting a completely wrong answer.
