Tangent
In geometry a straight line that touches a curve is called a tangent.
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.
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.

It is a tangent line
tangent
A tangent line touches a curve or the circumference of a circle at just one point.
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.
It is a straight line that touches the curve such that the line is perpendicular to the radius of the curve at the point of contact.
A tangent line.
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.
Tangent:In geometry, the tangent line (or simply the tangent) is a curve at a given point and is the straight line that "just touches" the curve at that point. As it passes through the point where the tangent line and the curve meet the tangent line is "going in the same direction" as the curve, and in this sense it is the best straight-line approximation to the curve at that point.Chord:A chord of a curve is a geometric line segment whose endpoints both lie on the outside of the circle.
A tangent at that point where a straight line just touches a curve and a secant line when the straight line bisects the curve.
