In the Euclidean space , denote the set of all points with integer coordinate by . For any two-dimensional simple lattice polygon , we establish the following analogy version of Pick’s Theorem, , where is the number of lattice points on the boundary of in , is the number of lattice points in the interior of in , and is a constant only related to the two-dimensional subspace including .
