Indeed, the term  Rubaiyat  by itself has come to be used to describe the quatrain rhyme scheme that FitzGerald used in his translations: AABA. However, as a translation of Omar Khayyam's quatrains, it is not noted for its fidelity.arim Emami 's translation of the Rubaiyat was published under the title The Wine of Nishapour in Paris. The Wine of Nishapour is the collection of Khayyam's poetry by Shahrokh Golestan, including Golestan's pictures in front of each poem.
An angle equal to 14 turn (90Â° or Ï2 radians) is called a right angle. Two lines that form a right angle are said to be normal, orthogonal, or perpendicular. Angles larger than a right angle and smaller than a straight angle (between 90Â° and 180Â°) are called obtuse angles (obtuse meaning blunt).
Facts about right angles. Four right angles fit around a point. The way we define degrees, a full turn around a point is 360Â°, so the measure of each right angle is one fourth of that: 90Â°. In informal speech (not mathematics), right-angle corners are sometimes called square corners even though, as in the shapes above, there is nothing square about the shape.
