# Triangulation - Use [[convex-hull|Graham's scan]] to derive the triangulation. Keep track of all the intermediate triangles. - Maximize the minimum angles in the triangles to achieve minimum math error. - Delauney triangulation - Voronoi Diagram - Bipartite lines - Calculate intersection of the half planes - Post office problem, calculate bisector between a post office and all the other offices. -- $O(n^2)$ time
