How can you find the area of a lattice polygon just by counting points? Pick’s Theorem says: Area = I B/2 – 1 I = number of interior lattice points B = number of boundary lattice points Count them, plug into the formula — and you get the exact area, no geometry needed! #math #mathematics #mathchallenge #mathtrick #education
