The points are $\"\"$ .

\

Let $\"\"$ , $\"\"$ and $\"\"$ .

\

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

\

If the three points are collinear, then the angle between $\"\"$ and $\"\"$ will be $\"\"$ or $\"\"$ .

\

Now, find the component from each vector :

\

$\"\"$

$\"\"$

$\"\"$

\

Use the formula for the angle between two vectors.

$\"\"$

\

$\"\"$

\

$\"\"$

\

Since the angle between the vectors is about $\"\"$ , the points are not collinear.

\

$\"\"$

\

No.
