What is difference between collinear & coplanar vectors ?
If vector AO + OB = vector BO + OC , then A , B , C are coplanar or collinear ?
they are maybe collinear but they are guaranteed coplanar unless you are not studying them in 3D geometry
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
is this question based on maharastra textbooks
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
