Recall the types of vectors.

Sometimes

Practice makes perfect

Let's begin with recalling the types of vectors.

Type	Direction	Magnitude
Parallel Vectors	same or opposite	not necessarily
Opposite Vectors	opposite	same
Equivalent Vectors	same	same

We are asked to determine if parallel vectors are sometimes, always, or never opposite vectors. From the table, we can see that parallel vectors can have opposite direction and the same magnitude but not necessarily. Therefore, parallel vectors are sometimes opposite vectors.
