ArrangementApproximateTraits_2 Concept Reference
Traits Concepts

## Definition

The concept `ArrangementApproximateTraits_2` refines the basic traits concept `ArrangementBasicTraits_2`. A model of this concept is able to approximate a point.

Refines:
  `ArrangementBasicTraits_2`

Has Models:

  `CGAL::Arr_conic_traits_2<RatKernel,AlgKernel,NtTraits>`

  `CGAL::Arr_non_caching_segment_traits_2<Kernel>`

  `CGAL::Arr_segment_traits_2<Kernel>`

  `CGAL::Arr_polycurve_traits_2<GeometryTraits_2>`

  `CGAL::Arr_polyline_traits_2<SegmentTraits_2>`

  `CGAL::Arr_rational_function_traits_2<AlgebraicKernel_d_1>`

Has Models:
  `CGAL::Arr_linear_traits_2<Kernel>`
