Triangle law of vector addition

  If two vectors are represented by both magnitude and direction by two sides of a triangle taken in the same order then their resultant is represented by  side of the triangle. 

The figure represents the triangle law of vector addition

So resultant  side C is given by 

 

Where = angle between two vectors.

Parallelogram law of vector addition 

 

  • If two vectors are represented by both magnitude and direction by two adjacent sides of the parallelogram taken from the same point then their resultant is also represented by both magnitude and direction taken from the same point but by diagonal of the parallelogram.

 The figure represents the law of parallelogram vector Addition
