Simple definition: A shape with no corners but instead, a continuous curve that ends exactly where it begins. Note: It can be very hard to draw a perfect circle by hand. Many people use an object to trace around, such as a drinking glass or a jar. More complicated definition: The set of all points in a plane that are a certain distance from a single point. A circle is the set of all points a given distance from a given point. The given point is termed the "center" of the circle. A straight line from the center to the circumference.
Circle is the locus of points equidistant from a given point, the center of the circle. The common distance from the center of the circle to its points is called radius. Thus a circle is completely defined by its center O and radius R :. This definition that appears so natural to a 21 st century reasonably educated person is markedly different from the one given by Euclid Definition I. In Sir Heath's translation:. A circle is a plane figure contained by one line such that all the straight lines falling upon it from one point among those lying within the figure are equal to one another. A circle is a plane figure contained by one line, which is called circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference, are equal to one another.
The length of a chord that contains the center of the circle. That's called the 'radius'. The diameter of a circle is twice its radius or its largest chord passing through the center of the circle. That "same distance" is the radius of the circle, and that "given point" is the center of the circle. Circle Graph A positive real number. It can be irrational or rational, even integer.
Not before long, I think about four cops went up to the circle and just grabbed a few of the people from behind. It caused people to drive around all night in a circle , and not eat.

A circle is a simple closed shape. It is the set of all points in a plane that are at a given distance from a given point, the centre ; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The distance between any of the points and the centre is called the radius. This article is about circles in Euclidean geometry , and, in particular, the Euclidean plane, except where otherwise noted. A circle is a simple closed curve that divides the plane into two regions: an interior and an exterior.
