If `veca,vecb` represent the diagonals of a rhombus, then

If veca and vecb are adjacent sides of a rhombus, then veca.vecb=0

If vecaandvecb are adjacent sides of a rhombus, then veca.vecb=0 .

State true or false: If vecaandvecb are adjacent sides of a rhombus, then veca.vecb=0 .

If veca and vecb represent a side and a diagonal of a parallelogram, find the other sides and the other diagonal.

Let veca=2hati-4hatj+5hatk and vecb=hati-2hatj-8hatk be two vectors Find a vector vecc representing a diagonal of the parallelogram with veca and vecb as the adjacent sides.

If the diagonal of a rhombus are equal, then the rhombus is a

Vector vecA - vecB represents -
