Solution: We model the triangular grid using a coordinate system adapted to equilateral triangles, but the problem simplifies: we interpret lattice points inside a large equilateral triangle of side length 6 in a triangular lattice where vertices are at lattice points and side length corresponds to 6 units. However, for computational geometry in such grids, the classic approach uses area and Pick’s Theorem.
