Pick's theorem expresses the area of a polygon with all its vertices on lattice points in a coordinate plane in terms of the number of lattice points inside the polygon and the number of lattice points on the sides of the polygon. The formula is:
with 
being the number of interior lattice points, and 
being the number of lattice points on the boundary.
Proof
