They're concentric circles. But I don't think they even need to be coplanar in order to be concentric.
Tangent circles.
Circles in the same plane with the same center are concentric circles.
concentric circles
coplanar
Difficult to tell since there is nothing following. My guess is concentric, but that does not require the circles to be coplanar.

Concentric Circle
Any two non-overlapping circles.
Tangential circles.
They're definitely similar, concentric, and coplanar. They're not necessarily congruent, but they could be.
When the centers of both the circles are at the same point.
Tangent circles.
Tangential circles.
concentric
AnswerThat would be circles with different sizes, having the same center.AnswerConcentric circles have a common center and different radii.Bulls eye could be an example of concentric circles.ans; Concentric circles are nothing but 2or more circles having common center but having different radius.Source: www.icoachmath.com
Correct.
