Collinear Points Using Determinants

Additional Resources:

In this lesson, we will learn how to determine if three points are collinear using determinants. In the last lesson, we looked at how we could find the area of a triangle using determinants. Here, we will rely on the same formula and look for a specific result. Basically, if this formula evaluates to zero, this tells us the three points are collinear or lie on the same line.
