Question

give definition of
equal vector
parallel vector
anti parallel vector​

Answer 1

Explanation:

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°

Answer 2

Answer:

equal vector :-

vectors which are equal in magnitude and direction. Note that when the vectors are equal, the directed line segments are parallel.

parallel vector :-

Parallel vectors are vectors pointing in the same direction whereas anti-parallel vectors are those pointing exactly opposite to each other.

anti parallel vector​ :-

Two vectors are said to be anti-parallel when they point in exactly opposite directions either along the same line or on parallels.
