When it comes to identifying and plotting circles, it's key to understand the structure of their equation, which is typically in the form of (x-h)² + (y-k)² = r². In this equation, (h,k) denotes the center of the circle, while r signifies the radius. To graph the circle, one must first mark the center on the graph and then uniformly measure the radius in all directions from this point.
