Question:medium
If $|\mathbf{a} + \mathbf{b}| = |\mathbf{a} - \mathbf{b}|$, then $\mathbf{a}$ and $\mathbf{b}$ are
If $|\mathbf{a} + \mathbf{b}| = |\mathbf{a} - \mathbf{b}|$, then $\mathbf{a}$ and $\mathbf{b}$ are
Show Hint
$|\mathbf{a}+\mathbf{b}| = |\mathbf{a}-\mathbf{b}|$ implies $\mathbf{a} \perp \mathbf{b}$. Geometrically, this is the condition for diagonals of a rectangle to be equal.
