Tangent, in geometry, is used to describe when figures have only one point in common. In Trig. tangent is applied to triangles.
The tangent of an angle is a ratio so, if you mean pi, and not pie, then it is simply a product of two ratios.

Tangent can mean: a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point. Today in maths we studied tangents. Or tangent can mean: a completely different line of thought or action. The discussion went off at a tangent and we never resolved the problem.
A departure from the subject under consideration
Assuming that you mean degrees, the answer is 1.
It is a straight line that touches the circle.
honestly yes

A tangent to a circle is a line which touches the circle once. That is, it does not pass through the circle, which would mean intersecting it twice. A way to form a tangent is draw any line from the centre point of a circle to its edge. A line on the edge perpendicular (at 90 degrees to) this line will be a tangent.
