Great question! The center of a circle circumscribing a triangle can indeed lie outside the triangle. Consider a simple example: The center of the circle square(x)+square(y)=2 is the origin. Consider a triangle formed by three points on this circle (1, 1), (-1, 1) and (0, sqrt2). The center (0, 0) of the circumscribing circle clearly lies outside the triangle. The problem in this video is similar. Plotting to scale (which I have not done in my explanation) will help make it clearer. Hope this helps.

Where the crap did the 6 come from that you threw in there? I got everything, right up until that point.... I get why it is there, but where did it come from?

do the points really create a triangle? because i graphed it but i only got a straight line :/

This is so hard to understand. Numbers from next equation just pop up before our eyes without further explanation.
