The class Delaunay_mesh_criteria_2<CDT> is a model for the MeshingCriteria_2 concept. The shape criterion on triangles is given by a bound B such that for good triangles (r)/(l) ≤ B where l is the shortest edge length and r is the circumradius of the triangle. By default, B=√2, which is the best bound one can use with the guarantee that the refinement algorithm will terminate. The upper bound B is related to a lower bound αmin on the minimum angle in the triangle:
