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).
Right angles have their own symbol, which is a square in the corner where the two lines of the angle meet. Math has six kinds of angles: acute, right, obtuse, straight, reflex and full. Acute and obtuse angles are defined in relation to right angles, as acute angles are less than 90 degrees and obtuse angles are between 90 and 180 degrees. A straight angle is exactly 180 degrees, and a full angle is exactly 360 degrees. Reflex angles fall between 180 and 360 degrees.
