The points are $\"\"$ , $\"\"$ , $\"\"$ and $\"\"$ .

\

The vectors are $\"\"$ and $\"\"$ .

\

Find the component form of $\"\"$ :

\

$\"\"$

\

Find the magnitude of the vector $\"\"$ :

\

$\"\"$

\

Direction of the vector $\"\"$ :

$\"\"$

\

Find the component form of $\"\"$ :

\

$\"\"$ and $\"\"$ .

\

$\"\"$

\

Find the magnitude of the vector $\"\"$ :

\

$\"\"$

\

Direction of the vector $\"\"$ :

\

$\"\"$

\

$\"\"$

\

Since magnitude and direction for the both vectors $\"\"$ and $\"\"$ are same.

\

Therefore, $\"\"$ and $\"\"$ are equivalent.
