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.
