In this paper, we investigate the properties of fuzzy spheres and estabilish convergence theorems of them. We expect that convergence theorems of fuzzy spheres may be useful for computer graphics and patten recognition.

The concept of a circularity function is used in defining fuzzy spheres The circularity function of a fuzzy sphere converses to one of crisp sphere as the fuzzy sphere shapes itself more and more like a crisp sphere.

In this paper, we introduce the intuitionistic fuzzy circle with a pair of degree which are membership and nonmembership functions, and investigate the properties of them. And also we experiment with developing fuzzy geometry by limiting process of the notion of intuitionistic fuzzy circles which restricted the notion of fuzzy spheres in order to apply to 2-D image.
