RectangularPCenterTraits_2::Construct_point_2_above_right_implicit_point_2 3-argument function class: Point_2  × Point_2  × FT  Point_2. For arguments (p,q,r) it returns the upper-right corner of the iso-oriented square with sidelength r and lower-left corner at the intersection of the vertical line through p and the horizontal line through q. RectangularPCenterTraits_2::Construct_point_2_above_left_implicit_point_2 3-argument function class: Point_2  × Point_2  × FT  Point_2. For arguments (p,q,r) it returns the upper-left corner of the iso-oriented square with sidelength r and lower-right corner at the intersection of the vertical line through p and the horizontal line through q.
