Click For Summary
Two vectors are considered parallel if they point in the same or opposite directions. To determine if vectors are parallel, one can analyze their directionality and magnitude. If the vectors are scalar multiples of each other, they are also parallel. This means that one vector can be expressed as a constant multiplied by the other. Understanding these concepts is essential for solving problems involving vector relationships.
