Vector Geometry

Overview

A vector has both size and direction, which makes it the natural way to describe movement, force or displacement. Adding vectors lets you combine journeys or pushes, and expressing one vector in terms of others is a powerful way to prove geometric facts.

In this lesson (Extended tier) you will represent vectors by directed line segments, use position vectors, add and subtract vectors to express others in terms of two given vectors, and use vectors to reason about geometry.

Objectives

  1. Represent vectors by directed line segments.
  2. Use position vectors.
  3. Use the sum and difference of two or more vectors to express given vectors in terms of two coplanar vectors.
  4. Use vectors to reason and to solve geometric problems.

Lesson Note

Vectors capture direction as well as size, which scalars cannot. They are the language of motion and force in physics and a clean tool for geometric proof.
