Answer :
Parallelogram law of vectors : If two vector quantities are represented by the two adjacent sides of a parallelogram, then the diagonal o the parallelogram will be equal to the resultant of the two vectors.
Triangle law of vectors : Triangle law of vectors states that if two vectors are represented by two sides of a triangle taken in the same direction then the third side will represent the resultant of the vector taken in the opposite direction.
