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.
An infinite number. / There is no limit.
Only one which is a tangent to that circle.
no; for example, a circle and a circle within that circle have no common tangents.
Always one for sure, and never more than one.
An infinite amount
If the tangents are parallel, they must be on opposite ends of a diameter.They are 8 cm apart.
If you draw tangents to a circle at opposite ends of a diameter, those two tangents are parallel. No matter how far you extend them, they'll never meet.

Two tangents can be drawn from a point outside a circle to the circle. The answer for other curves depends on the curve.
WHAT ARE THE TANGENTS OF ALL COORDINATES IN THE UNIT CIRCLE?
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.
An infinite number. / There is no limit.
No tangent No tangent
Only one which is a tangent to that circle.
no; for example, a circle and a circle within that circle have no common tangents.
That depends on what question you have been asked concerning the two tangents. All by itself, a circle with two tangents is quite content, and isn't looking for a solution.
