How to Find Distance in GeoGebra
It is easy to find distances between points, lines and planes in GeoGebra. The only thing that requires a little extra work is to find the distance between a line and a plane. To find this distance you need to find a point on the line, and insert this point in the instructions below for the distance between point and point, line or plane. This is similar to the method of doing this by hand.
GeoGebra Instruction 1
Distance Between Point and Point, Line or Plane
- 1.
- Open
Algebra Viewand3D Graphicsunder
Viewin
Menu. - 2.
- Enter your point and the other object (a second point, line, or plane)
Note! To use a line, it must be entered with the
Linecommand. - 3.
- Enter
Distance(<Point>, <Object>)
in
Algebra View. Fill in your point for<Point>and the point, line or plane for<Object>. - 4.
- The distance is now shown in
Algebra View.
GeoGebra Instruction 2
Distance Between Two Lines
- 1.
- Open
Algebra Viewand3D Graphicsunder Viewin Menu. - 2.
- Enter both of your lines using the
Linecommand. This command has to be used in order for theDistancecommand to work in the next step. - 3.
- Enter
Distance(<Line>, <Line>)
Fill in the names of the two lines.
The distance is now shown in
Algebra View.
GeoGebra Instruction 3
Distance Between Two Planes
- 1.
- Open
Algebra Viewand3D Graphicsunder Viewin Menu. - 2.
- Enter both of your planes either by using the commands in the entry about lines and planes, or define them in
Algebra Viewusing their equations. - 3.
- Enter
Distance(<Plane>, <Plane>)
Fill in the names of the two planes.
The distance is now shown in
Algebra View.
