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 are defined as those angles that measure exactly 90 degrees. The most important place you will see them is in triangles. The formula that comes from the right triangle is the Pythagorean Theorem that relates all the sides of the right triangle to each other.
