A tangent, but it (a) has nothing to do with croosing (whatever that may mean); and (b) while it does not cross the curve in the neighbourhood of the point of contact - there is no restriction on it crossing the curve at a distance.
In geometry a straight line that touches a curve is called a tangent.
The term you're looking for is "tangent." In geometry, a tangent is a straight line that touches a curve at a single point, known as the point of tangency, and continues on without crossing the curve at that point. Tangents are often discussed in relation to circles and other curves, where they represent the instantaneous direction of the curve at the point of contact.
tangent
A tangent is a straight line that touches the circumference of a circle at a given point
Tangent
It is a tangent line
A tangent line touches a curve or the circumference of a circle at just one point.
In geometry a straight line that touches a curve is called a tangent.

Tangent
A straight line that touches a curve but continues without crossing it is called a "tangent." At the point of contact, the tangent line has the same slope as the curve, indicating that it just grazes the curve rather than intersecting it.
In geometry a Tangent is a straight line that just touches the circumference of a circle.
tangent
if it touches at three points it is a straight line. Since it is also an asymptote, it will be a straight horizontal line (zero slope)
