Question

Which is a secant of circle A?

(Points : 1)
segment AB

line DE

segment HG

line CD

Answer 1

The correct option is line CD

Explanation:

Given the diagram we have to find the secant of circle A.

Secant of a circle is a line intersecting the circle at exactly two different points and a chord is the line determined by these two.

In the circle A the only line intersect two different points is CD and the interval on a secant is the chord of circle.

Here, HG is only the chord of circle not secant.

Hence, the correct option is line CD

Answer 2

A line passing through two points on a circle is called a secant. Therefore, the correct answer from the choices listed above is the last option. Line CD is the secant of circle A. It is clear that it is a line that passes through two points in the circle. Hope this answers the question.
