What are Concentric Circles?
Concentric circles are a collection of circular shapes positioned such that they all share the same central point but have varying sizes as determined by their respective radii. These circles are akin to a set of ripples expanding outward from a singular source, or like a series of nested circular boundaries within one another.
They maintain a symmetrical arrangement around a common center, resembling a target board or a bullseye pattern, and are frequently employed in various fields, including mathematics, engineering, and design, to depict proportional relationships or as a visual aid in illustrating concepts like depth, layers, or spatial hierarchy.

Concentric Circles Meaning
Concentric circles are circles that share the same center but have different diameters or radii. Picture multiple circles, one inside the other, like a target board. They all have the same midpoint, but their sizes vary. These circles don’t touch each other; they’re just nested within one another. The term “concentric” essentially means having a common center.
Concentric Circles
Concentric circles are defined as two or more circles that share the same center point, known as the midpoint, but each has a different radius. If circles overlap yet have different centers, they do not qualify as concentric circles. According to Euclidean Geometry, two concentric circles must have two different radii. The space between the circumference of these two circles is called the annulus of a circle.
