The law is used to add vectors to find the resultant of two or more vectors acting at a point.
12 vectors, unless it is a parallelogram (13 if you include the null vector). If the quadrilateral is a parallelogram there will be two fewer.
If the vectors form a polygon, their sum is zero..
To add two vectors that aren't parallel or perpindicular you resolve both of the planes displacement vectors into "x' and "y" components and then add the components together. (parallelogram technique graphically)
Use the parallelogram method to add two of the vectors to create a single vector for them;Now use this vector with another of the vectors to be added (using the parallelogram method to create another vector).Repeat until all the vectors have been added.For example, if you have to add V1, V2, V3, V4 do:Used method to add V1 and V2 to result in R1Use method to add R1 and V3 to result in R2Use method to add R2 and V4 to give final resulting vector R.
"If two vector quantities are represented by two adjacent sides or a parallelogram then the diagonal of parallelogram will be equal to the resultant of these two vectors."
parallelogram method is a common way of adding two vectors

The parallelogram law states that the sum of squares must equal the sum of its four sides. These equations are very complex and hard to understand.
Given two vectors a and b, the area of a parallelogram formed by these vectors is:a x b = a*b * sin(theta) where theta is the angle between a and b, and where x is the norm/length/magnitude of vector x.
Vectors can represent anything that has both magnitude and direction, like velocity, acceleration, momentum, force, etc.
The answer is in the definition: polygon of forces(plural polygons of forces) # (mechanics) A polygonal figure the sides of which are vectors representing several forces acting simultaneously upon one point, so that the vector necessary to make the figure closed is the resultant of those forces.
If the vectors form a polygon, their sum is zero..
add both forces
No, it is simpler than that. Simply add the two magnitudes. The direction will be the same as the parallel vectors.
