How to Write the Equation of a Circle Given Three Points

When given three points, there is only one possible circle that passes though all of those points. In this video, I describe the algebra that can be used to write the equation of that circle in standard form.

This video assumes you already have a basic understanding of the equations of circles. However, the algebra required to solve problems like this is fairly basic.
