A tangent line touches a curve or the circumference of a circle at just one point.
A tangent line.
It is called a tangent.
The diameter of a circle or sphere is the length of a straight line that touches both sides and passes through the centre.
A straight line that intersects a circle or curve at two points, but which has both end points outside the circle or curve is called a secant. A straight line that links two points on a circle or curve is called a chord. A straight line which touches a circle or curve at one point is called a tangent. A straight line that cuts a circle or curve at one point is a straight line.* For moving diagrams see Related links below this box.
A tangent is always perpendicular to the radius of a circle. A radius is a straight line going from the center of the circle to the circumference (edge) of the circle. A tangent is a straight line outside the circle that touched the circle at one (and only one) point. When a tangent touches the outside edge of the circle at the same point where a radius touches the edge of the circle, the angle between the radius and tangent line is 90 degrees meaning they are perpendicular.

A tangent line.
Tangent
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.
tangent
A tangent is a straight line that touches the circumference of a circle at a given point
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)

It is the tangent of the circle
It is a straight line that touches the circle.
