What is difference between collinear & coplanar vectors ?
If vector AO + OB = vector BO + OC , then A , B , C are coplanar or collinear ?
collinear vectors means that they have lie on any line which are common in them
but coplanar means they lie in a plane such as x-y plane our cartesian coordinate system like that
they are maybe collinear but they are guaranteed coplanar unless you are not studying them in 3D geometry
They are collinear if AO =AC else they are coplanar
Since vector AO+OB=BA
and vector BO+OC=CB
both the vectors have a common point B therefore they are collinear
