Segol Segol Segol ( ) is a Hebrew niqqud vowel sign that is represented by three dots forming an upside down equilateral triangle "ֶ ". As such, it resembles an upside down therefore sign (a because sign) underneath a letter. In modern Hebrew, it indicates the phoneme which is similar to "e" in the English word sound in "sell" and is transliterated as an "e". 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. The following table contains the pronunciation
Reuleaux triangle any curve of given constant width. This area is where "s" is the constant width. One method for deriving this area formula is to partition the Reuleaux triangle into an inner equilateral triangle and three curvilinear regions between this inner triangle and the arcs forming the Reuleaux triangle, and then add the areas of these four sets. At the other extreme, the curve of constant width that has the maximum possible area is a circular disk, which has area formula_2. The angles made by each pair of arcs at the corners of a Reuleaux triangle are all equal to 120°.
