Congruent circles, maybe...
Yes. They would be exactly the same, and one on top of the other.

The circles are "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.

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.
Two circles that don't have the same center point are called "non-concentric circles." These circles can have different radii and may or may not intersect each other. If they intersect, they will do so at two points, one point, or not at all, depending on their sizes and positions.
