What is the relationship between a secant and a chord?

The relationship between a secant and a chord is that a secant can also be a chord, which means that they share similar characteristics in certain conditions.

A secant is defined as a line that intersects a circle at two points, while a chord is a line segment whose endpoints lie on the circle. When a secant intersects the circle, the portion of the secant that lies within the circle (the segment between the two intersection points) is actually a chord. Therefore, every secant that intersects the circle provides a specific chord.

This relationship underlines the concept that a secant can act as a chord depending on the context of its position relative to the circle. Other options do not accurately represent the relationship between secants and chords in terms of their definitions and properties.
