A circle is a simple closed shape in Euclidean geometry. 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 so that its distance from a given point is constant. The distance between any of the points and the centre is called the radius.
René ( born again or reborn in French) is a common first name in both French-speaking and Spanish-speaking countries. It derives from the Latin name Renatus.
