In Modern Hebrew, segol does the Hataf Segol ( , "Reduced Segol"). The reduced (or "ħataf") niqqud exist for segol, patah, and kamatz which contain a shva next to it.

Reuleaux triangle set of three-diameter points of any other curve of constant width. Although the Reuleaux triangle has sixfold dihedral symmetry, the same as an equilateral triangle, it does not have central symmetry. The Reuleaux triangle is the least symmetric curve of constant width according to two different measures of central asymmetry, the Kovner–Besicovitch measure (ratio of area to the largest centrally symmetric shape enclosed by the curve) and the Estermann measure (ratio of area to the smallest centrally symmetric shape enclosing the curve). For the Reuleaux triangle, the two centrally symmetric shapes that determine the measures of asymmetry are both hexagonal,
