The Maths Prof: Finding Equation of Circle (3 points on circumference given)

In this lesson I show you how to find the equation of a circle when given the coordinates of 3 points that lie on the circumference. The method I have used here is finding the intersection of perpendicular bisectors to find the centre of the circle and afterwards, the radius.
