Welcome to the next series of lessons in the world of coordinate geometry – Circle.

This will be one of the most interesting topics in coordinate geometry, as you’re already familiar with the circle from your earlier classes.

So here’s my lesson plan: I’ll be starting with the definition, followed by standard equations. Next, we’ll move on to tangents and normals. Finally, I’ll cover some advanced topics, including family of circles and radical axis.

Of course, you might not have any idea about some of the terms I just used, but soon you will. Each topic will be followed by a few solved problems, and a few unsolved ones for practice.

So let’s get started! See you soon with the first lesson.
