How to Check If Two Vectors are Parallel Using GeoGebra
There are two ways to find out if two vectors are parallel in GeoGebra
. One is simply to solve the vector equation in CAS
. The other is to draw two lines and use a GeoGebra
command to check if the they are parallel.

. Line(<Point>, <Direction Vector>)
in Input Bar
. Fill in (0,0)
for <Point>
and one of the vectors for <Direction Vector>
. Press Enter
. The line should now be shown Algebra View

.
AreParallel(<Line>, <Line>)
in Algebra View
. Fill in your two lines and press Enter
. If true
is displayed in Algebra View
, the vectors are parallel. Ff false
is displayed in Algebra View
, the vectors are not parallel.
