Often circles lines points et cetera are named.
In this answer I call the circle C, the Tangent T, the point P, the center of the circle O
They are called just what your question asked:
"The tangent to circle C through point P is T"
P may not be inside C but may be on C
If P is outside C there are twotangents T1 and T2
If P is on C there is one tangent T
T is perpendicular to the radius at the point of tangency
Only one which is a tangent to that circle.
Yes, the point at which a tangent line intersects a circle is indeed called the point of tangency. At this point, the tangent line touches the circle at exactly one location, and it is perpendicular to the radius drawn to that point. This relationship is fundamental in geometry, particularly in the study of circles and tangents.
it can be used to draw tangents from a given point on a circle.
They're equal, 12 cm long.
no; for example, a circle and a circle within that circle have no common tangents.
Two tangents can be drawn from a point outside a circle to the circle. The answer for other curves depends on the curve.
Any tangent must contain a point outside the circle. So the answer to the question, as stated, is infinitely many. However, if the question was how many tangents to a circle can be drawn from a point outside the circle, the answer is two.

No tangent No tangent
Only one which is a tangent to that circle.
WHAT ARE THE TANGENTS OF ALL COORDINATES IN THE UNIT CIRCLE?

Tangents ..... are parallel under conditions you gave. A tangent to a circle is perpindicular to the radius (diameter) at the point of contact. 2 lines perpindicular to the same line are parallel.
None. A tangent is a line that has exactly onepoint in common with the circle.If it contained a point inside the circle, then it would have to pass through twopoints on the circle.
Always one for sure, and never more than one.
