In figure (a square), identify the following Vectors:
(i) Coinitial
(ii) Equal
(iii) Collinear but not equal
(i) Vectors a and d are coinitial because they have the same initial point.
(ii) Vectors b and d are equal because they have the same magnitude and direction.
(iii) Vectors a and c are collinear but not equal. Although they are parallel, but their directions are not same.
