- Distance[ <Point>, <Object> ]
- Yields the shortest distance between a point and an object.
- Example:
Distance[(2, 1), x^2 + (y - 1)^2 = 1]yields 1
- Note: The command works for points, segments, lines, conics, functions and implicit curves. For functions it uses a numerical algorithm which works better for polynomials.
- Distance[ <Line>, <Line> ]
- Yields the distance between two lines.
- Example:
Distance[y = x + 3, y = x + 1]yields 1.41Distance[y = 3x + 1, y = x + 1]yields 0
- Note: The distance between intersecting lines is 0. Thus, this command is only interesting for parallel lines.

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 |
