Question

give definition of
equal vector
parallel vector
anti parallel vector​

Answer 1

Equal vectors are vectors that have the same magnitude and the same direction. Equal vectors may start at different positions.

Vectors are parallel if they have the same direction. Both components of one vector must be in the same ratio to the corresponding components of the parallel vector.

Antiparallel vectors. In a Euclidean space, two directed line segments, often called vectors in applied mathematics, are antiparallel, if they are supported by parallel lines and have opposite directions. In that case, one of the associated Euclidean vectors is the product of the other by a negative number.

equal equal vectors are those vector which have equal magnitude and same direction angle between them is 0. parallel vectors are those vector which have same directions and angle between them is zero. antiparallel vectors are those vector which have opposite direction and angle between them is 180°....
