"Concentric" means to have a same centre. Concentric figures or objects share a common centre, axis or origin with one inside the other. Concentric circles are circles of different sizes which have a common centre. In other words we can say that, two or more circles which share the same centre are called concentric circles. Concentric circles have same centre but different radii, for it the radius is same they become equal. Since the concentric circles have different radii and same centre, they are at the same distance apart all the way around and they fit inside each other.
The picture above shows the concentric circles (5 circles) with centre “C”.
The best example for concentric circles is the evenly spaced circles of a target used in target archery or firearms. The centre of these concentric circles is called the “bulls eye” in target archery or the dart game.
