when two forces act in the same straight line (nasf il itijah ..... mithil 2ai parallel lines ) then u get the resultant force by adding the two forces.
but as for the parallelogram , the resultant force is the diagonal of the parallelogram ...here is the rule from my book :
Oh sure thing np ..wait a sec so that i get the book.
In my book it says :
if the two forces acting at a point are represented in size and direction by the sides of a parallelogram drawn from the point ,their resultant is represented in size and direction by the diagonal of the parallelogram drawn from the point.
I hope u got it , if u didn't let me kno.

i get the part about the parallel and ones in diferent diirections,i dont get ones that are right angles to each others

Well then check this out ;)

OK I really hope this helps you. Sorry it's really scruffy and not you fault if you find it difficult to comprehend.
Just follow 1-2-3-4-5-6. I think you should get it. It's from one of the past papers that I'd used to solve a similar doubt earlier.
Past papers will be out on the 12th or the 13th of this month. That is when the results for this are out too. ;)
