Circles are one of the most important shapes in are history. Circles where found back in the cave man times. We use circles for important things such as: car tires, wheels, baskeballs, and etc.... Without circles we wouldent be able to get any where. So be greatful for the circle in your life

A circle is a simple shape of Euclidean geometry consisting of those points in a plane that are a given distance from a given point, the centre. The distance between any of the points and the centre is called the radius. http://en.wikipedia.org/wiki/Circle

Yes, a circle isn’t something that exists in nature. It isn’t something that people discovered like gold or the new lands of America. It is a mental construct, a symbolic representation that was invented much the same as language and the alphabet.

There is no way to be certain, but anthropologists generally agree that the circle was created long before recorded history. It is quite likely that it was drawn by a stick in the sand. With the sun being a constant in early man’s existence and the source of all life, it is quite likely that the first circle represented the sun http://circlesonly.wordpress.com/category/history-of-circles/
