Understanding Circles and Their Properties

This video tutorial delves into the concept of circles, explaining how they are formed by a set of points equidistant from a center point. It covers the geometrical and algebraic representations of circles, including deriving the general equation of a circle and the specific case when the circle's center is at the origin. The video concludes with a summary and a preview of solving examples in the next video.
