The diagram which shows the parallelogram method for vector addition is shown in the image attached below.
In this scenario, let the two (2) vectors representing the two (2) adjacent sides of a parallelogram in both magnitude and direction drawn from a common point be:
The parallelogram law of vector addition states that if two (2) vectors
and
represent the two (2) adjacent sides of a parallelogram in both magnitude and direction drawn from a common point, then their sum
or resultant vector (
) is equal to the diagonal of the parallelogram passing through that point in both magnitude and direction.
Therefore, the diagram which shows the parallelogram method for vector addition is shown in the image attached below.
