How to Graph a Vector of Given Length in GeoGebra

These instructions are intended more as a general guide than something you will use directly on exams or assignments. However, you may have a great benefit of following these instructions when you need to illustrate vectors of given lengths.

GeoGebra Instruction 1

1.
Select the Circle: Center & Radius GeoGebra icon tool from the list in the sixth pane.
2.
Click on the point the vector should start. A box pops up. Enter the length of the vector.
3.
Choose the tool Point on Object GeoGebra icon. Click on the circle.
4.
Select the Vector GeoGebra icon tool. Click on the center of the circle, and then press the point on the circle where you want the vector to go.

You have now drawn a vector of a given length.
