In mathematics, a fixed-point theorem is a result saying that a function F will have at least one fixed point (a point x for which F(x) = x), under some conditions on F that can be stated in general terms. Some authors claim that results of this kind are amongst the most generally useful in mathematics.

A Fixed Point Theorem for Mappings which do not Increase Distances by W. A. Kirk (Source: The American Mathematical Monthly) WebA rotation in geometry is a transformation that has one fixed point. The geometric object or function then rotates around this given point by a given angle measure. This measure can be given in degrees or radians, and the direction — clockwise or counterclockwise — is specified. The most common point of rotation is the origin (0, 0).
