Question

Which of the segments below is a secant?

Answer 1

The secant of a circle is any line that intersects two points on the circumference of the circle.

In the given circle, the lines EF and XY intersects two points on the circumference of the circle and hence are secants of the circle.

From the answer options given, the secant line is line XY.

Answer 2

Answer:

Option A is correct.

Step-by-step explanation:

Secant:  Secant is line which intersect the curve at 2 points.

Option A :

$\overline{XY}$ is secant as according to definition it is intersecting the circle at exactly two points.

Option B :

$\overline{OB}$ is radius of circle as its a line from center to a point on circle.

Option C :

$\overline{XB}$ is tangent to the circle as it is line segment from an exterior point X to a point on circle B.

Option D:

$\overline{XV}$ is also a tangent to circle as it is line segment from an exterior point X to a point on circle V.

Therefore, Option A is correct.
