- Distance[ <Point>, <Object> ]
- Yields the shortest distance between a point and a geometric object, or the vertical distance to a function.
- Example:
Distance[(2, 1), x^2 + (y - 1)^2 = 1]
yields 1- Let f be a function and A be a point.
Distance[A, f]
yields the vertical distance between the point and the function.
- Note: The command works for points, segments, lines, conics and implicit curves.
- Distance[ <Line>, <Line> ]
- Yields the distance between two parallel 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.
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 |
