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 finding 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 using the instructions below for the distance between a point, and a point, line, or plane. This is similar to the method of doing so by hand.
GeoGebra Instruction 1
Distance Between a Point and a 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 by defining 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.
