Parallelogram Rule

Definition of Parallelogram Rule

Parallelogram Rule provides the means to perform vector addition of two vectors in two-dimensional space.

It is most easily understood in the two-dimensional model.
It is also called parallelogram law.

Example of Parallelogram Rule

Suppose two persons are pulling a load with a force f1 and f2 in two different directions from a fixed point. Then these forces can be represented as two sides of a parallelogram. By completing the parallelogram and using the parallelogram rule, the diagonal represents the sum of the two original forces f1 + f2.
