Question

Which of the following is correct for the circle given below?

• A. $AC$ is a tangent
• B. $AB$ is a secant
• C. $AC$ is a secant
• D. $AB$ is a tangent

Answer 1

Answer: (A), (B)

$AB$ is a secant

Concept: Tangent is a line that intersects a circle at only $1$ point while a secant intersects a circle at $2$ points.

• Here the line $AB$ intersects the circle at $2$ points which makes it a secant.
• And, the line $AC$ meets the circle at a single point, so this forms the tangent to the circle.

Hence options (1 and 2) are correct.
