Explanation

A tangent is a line that touches a circle at exactly one point. It is a limiting case of a secant where the two intersection points coincide.

AI explanation

A secant is a line that intersects a circle at two distinct points. When a secant is moved further away from the center such that the two intersection points merge into a single point of contact, it becomes a tangent. Therefore, a tangent is a special case of a secant.
