A chord.
It is called a secant line
That is a tangent line.
The intersection of a line and a circle is called a chord if the line intersects the circle at two points. If the line touches the circle at exactly one point, it is referred to as a tangent. If the line does not intersect the circle at all, it is considered to be external to the circle.
The tangent line intersects the circumference of a circle at just one point.

A tangent.
if that line segment intersects the centre of the circle it is called a radius.

The intersection of a line and a circle is called a chord if the line intersects the circle at two points. If the line touches the circle at exactly one point, it is referred to as a tangent. If the line does not intersect the circle at all, it is considered to be external to the circle.
A chord line intersects a circle at two points of which the circle's diameter is its largest chord.
Such a line is called a tangent line or a tangent to the circle. [Tangent is Latin for touching-- a tangent line touches the circle at just one point. ]
