concentric
A concentric circle.
Non concentric circles are circles that do not share the same center point.
No; tangent circles touch each other at one point but concentric circles cannot not touch.
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
A concentric circle.
Another circle midway between the originals.
If you mean they both have the same centre - they're called 'concentric' circles.
Non concentric circles are circles that do not share the same center point.
A circle inside another circle is called a concentric circle. This means that the circles share the same center point, with one circle contained entirely within the other.
No; tangent circles touch each other at one point but concentric circles cannot not touch.

There is such a point only if all the circles are concentric.

The difference between a stone keep castle and a concentric castle is that a stone keep castle had hardly any defence. The only defence was their high walls. But the concentric castles had loads of walls surounding them. The word 'concentric' actually means with common middle point: describes circles and spheres of different sizes with the same middle point.
Center. For example, if the point in the center of the circle was point O, then the circle would be named circle O.
