See It in Action
Two examples of the idea done right—and one common look-alike that is not right.

Definition
A vector is a quantity in Geometry that has both magnitude (length) and direction. It represents the movement from one point to another.
Key Points:
A vector is often written as〈a, b〉, where:
a is the horizontal change (left/right)
b is the vertical change (up/down)
Vectors are commonly used to describe translations.
They can be graphed as arrows that start at one point and point to another, showing the direction and distance of movement.
Vectors are not fixed in position — they describe movement, not location.
Example:
A vector〈3,-2〉moves a point 3 units right and 2 units down.
