Addition of vectors by graphical method
1) triangular law of vector addition
this law states that if 2 vectors can be represented in magnitude and direction by 2 sides of the triangle taken in the same order, then the resultant vector is represented by the other side of the triangle taken in the opposite order
2) this law states that if 2 vectors can be represented in magnitude and direction by the 2 adjusant sides of Parralelogram drawn from the same point, then the resultant vector is represented by the diagonal of the parralelogram passing from the same point
