To determine if $\"\"$ vectors are parallel or perpendicular, we can use the formula for the angle between $\"\"$ vectors.

If the angle measures $\"\"$ or $\"\"$ then the vector is considered as Parallel.

If the angle measures $\"\"$ then the vector is considered as Perpendicular.

$\"\"$

We can also find the component form of $\"\"$ vectors and use the ratio of coordinates to determine

if $\"\"$ vectors are parallel.

If the ratio of all the three coordinates of the component vectors are same then we can determine

that the vectors are Parallel.

To determine if the $\"\"$ vectors are perpendicular, we have to find the dot product of the vectors.

If the dot product is $\"\"$ then we can determine that the vectors are Perpendicular.
