The line doesn't touch the middle of circumfrance what is it called?

A line that does not touch the circumference of a circle is called a "secant" if it intersects the circle at two points, or an "external tangent" if it runs parallel to the circle without intersection. However, if the line is entirely outside the circle and does not intersect it, it is simply referred to as a "non-intersecting line" or "external line." In contrast, if a line touches the circumference at exactly one point, it is called a "tangent."
