To help you better understand the rational geometry system, definitions are given below. 2-D Definitions
    A rational point is any element of or a point of the form such that , and are rational numbers. A rational line can be written where and are rational numbers. A rational segment lies on a rational line and has rational endpoints. Rational polygons are defined by rational segments. A rational circle is the set of rational points satisfying , where , and are rational. 3-D Definitions
      A rational point is any element of or a point of the form where and are rational. A rational vector is a vector that connects two rational points. A rational line can be written where and are rational numbers. A rational plane is the set of all the rational points that satisfy the equation for rational . A sphere is the set of rational points satisfying , where and are rational. Functions A rational function can be expressed as where and and are polynomials with rational coefficients. Transformations A rational transformation is a rational function that maps one set of points to another.
