concentric
Concentric circles are the circles with the same center therefore they do not cross with each other as the "center is not considered a point on the circle". An exception would be two circles that are concentric and have the same radius, in which case the circles are indistinct and every point of the circles is an intersection.
In math, the word concentric means that two or more objects have the same center. For example, concentric circles are circles within a larger one. However, all the circles have a common center point.
concentric
Concentric circles have the same center. They are not necessarily the same size. If two concentric circles have the same area, then they are congruent, meaning they coincide when superimposed.
They are said to be concentric circles.
