Circle

A line can be described as an ideal zero-width, infinitely long, perfectly straight curve (the term curve in mathematics includes "straight curves" containing an infinite number of points. Circles are simple shapes of Euclidean geometry. A circle consists of those points in a plane which are at a constant distance , called the radius , from a fixed point, called the center. Giotto , ( c. 1267–January 8, 1337 ) drew, in red paint, a circle so perfect that it seemed as though it was drawn using a compass and instructed the messenger to give it to the Pope as proof of his skill. But down here is Leonardo da Vinci 's immortal circle. Man as the center of this 'simple shape' that raises the question: "Is the circle not a different kind of infinitly long line?" As it has no beginning and no end?
