ABCD is parallelogram `vecA, vecB, vecC and vecD` are the position vectors of vecticles A, B, C, and D with respect to any origin, them:

`vecA + vecB = vecC - vecD`

`vecC- vecB = vecA+ vecD`

`vec B- vecC = vecA - vecD`

`vecA + vecB + vecC+ vecD =0`

Text Solution

Verified by Experts

The correct Answer is:

`vecAvecB +vecCvecD= 0`
`(vecB - vecA) +vecD -vecC =0`
Sum of opposite sides = zero
