Distance[ <Point>, <Object> ]: Yields the (shortest) distance between a point and an object.; Note: The command works for points, segments, lines, conics and implicit curves. For a given function f and a given point A, the command Distance[A,f] yields the distance between A and (x(A),f(x(A))).

Distance[ <Line>, <Line> ]: Yields the distance between two parallel lines.; Note: The distance between intersecting lines is 0. Thus, this command is only interesting for parallel lines.; Note: See also Distance or Length tool .

Following text is about a feature that is supported only in GeoGebra 5.0.

Note: From GeoGebra 5, this command will work with 3D objects as well

-; Distance[Point A, Object O]: Yields the (shortest) distance between points ''A'' and the Object. Works for Points, Segments, Lines, Conics and Implicit Curves. When ''f'' is a function, <code>Distance[A,f]</code> returns distance between ''A'' and ''(x(A),f(x(A)))''.
+; Distance[ <Point>, <Object> ]: Yields the (shortest) distance between a point and an object.
-: {{Note| In GeoGebra 3.2  '''Distance[Point A, Segment]''' gave the distance to the segment extended to an infinite line. From GeoGebra 4.0 it gives the distance to the Segment itself. }}
