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: An angle whose measure is exactly 90Â°. Try this Adjust the angle below by dragging an orange dot and see how the angle â  ABC behaves. Note that it is a right angle only when its measure is exactly 90Â°. Right angles are one of the most common and interesting angles in all of geometry.It even has its own angle symbol. In the figure above, set the angle to 90Â° and see that instead of a small arc, the angle is marked with a small square symbol. If you see this, the angle measure in degrees is usually omitted.Note also that right triangles are those where one interior angle is a right angle.n the figure above, set the angle to 90Â° and see that instead of a small arc, the angle is marked with a small square symbol.
