  There exist precisely 11 distinct edge-to-edge tilings by regular polygons such that all vertices are of the same type, and these tilings are called Archimedean tilings. Pick's Theorem (1899) gives an elegant formula for the area of simple lattice polygons. Coleman Conjecture (1978) poses an inequality for numbers of lattice points in lattice polygons. We discuss the generalizations of the Pick's Theorem and the Coleman's Conjecture in Archimedean tilings.
