The video below is copied from Algebra 2, so if you're in Geometry, the math in the second half of the video may be more complicated than what you've seen. Feel free to skip, we just have to include the tough stuff too since some honors teachers are kind of aggro.

Circles

In this video we'll see how to graph circles from their equations, as well as how to get a circle's equation from its graph. We'll also check out the distance and midpoint formulas, and use them for a circle word problem. Finally, we'll use completing the square to put a random circle equation in standard form.
