Yes, circles that share one and only one point are tangent to each other.
Nothing "happens". They meet, and the rays continue merrily along their ways, never to meet again!
orgin? or intersection?
No, they meet at a single point.
3 and they meet in a single point called Circumcentre
If two circles are drawn using the same centre, the two lines of the circles are parallel as they don't meet each other.Two straight lines (think of railway tracks) are drawn next to each other, but never meet, they are parallel lines.
The radius and the tangent are perpendicular at the point on the circle where they meet.
Tangent.

Tangent:In geometry, the tangent line (or simply the tangent) is a curve at a given point and is the straight line that "just touches" the curve at that point. As it passes through the point where the tangent line and the curve meet the tangent line is "going in the same direction" as the curve, and in this sense it is the best straight-line approximation to the curve at that point.Chord:A chord of a curve is a geometric line segment whose endpoints both lie on the outside of the circle.
Tangent plane "is the floor". I never heard that the touching point has a specific name.
orgin? or intersection?
Ask you're parents!
No, they meet at a single point.
The answer depends on the context. In the context of a curve, a tangent is a straight line that touches the line without intersecting it. The antonym does not have a specific name because it could be a straight line that does not meet the curve at all, or it could be one that crosses the curve. Note that even a tangent can cross the curve at some other [distant] point(s).
If the lines are identical, then the whole lines. If not they can either not meet at all or at a single point: the point of intersection.
They don't. The Arctic and Antarctic Circles are parallel. Each circle has only a single latitude. The first is at 66.5° north latitude, 23.5° from the north pole. The second is at 66.5° south latitude, 23.5° from the south pole. They're 133° apart everywhere, and never meet.
