WebPolygon triangulation. In computational geometry, polygon triangulation is the partition of a polygonal area ( simple polygon) P into a set of triangles, [1] i.e., finding a set of triangles with pairwise non-intersecting interiors whose union is P . Triangulations may be viewed as special cases of planar straight-line graphs.
