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.
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.
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.
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.
2
No tangent No tangent
Only one which is a tangent to that circle.
WHAT ARE THE TANGENTS OF ALL COORDINATES IN THE UNIT CIRCLE?

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.
