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).
Definition. A right angle is an angle that measures exactly 90 degrees. It is exactly a quarter of a circle. When you cut a pie into four equal pieces, the tip of each slice will form a right angle. Look at the circle or 'pie' above and notice how the tips of each slice make a corner that is a right angle.ight Triangles. You will see right angles in many places. You will see them in squares and rectangles where each corner is a right angle. One of the most useful places you will see them is in triangles. When a triangle has a right angle, it becomes a special type of triangle called a right triangle.
