**geometric proof for vector relation-plz help!**

hi there....

i am trying to prove the following relation from vectors geometrically however nothing comes to my mind..i have succeeded in proving it algebraically.

CAN ANYONE help me as to how do i prove this relation geometrically.

The relation is:

**mag(A.B) <= mag A. mag B**

where A and B are vectors

and mag stands for magnitude
