Question

If $\overrightarrow{a}$ and $\overrightarrow{b}$ represents two adjacent sides of parallelogram then $|\overrightarrow{a}+\overrightarrow{b}|$ represents diagonal of parallelogram.
If true enter 1, else enter 0.

Answer 1

From the law of Parallelogram addition,

$\overline{R}=\overline{a}+\overline{b}$ Where $\overline{R}$ represent the vector of diagonal of parallelogram.

$\therefore |R|$= $|\overline{a}+\overline{b}|$ , it represent the length of the diagonal of the parallelogram.
