Question

question 6 of 10
which of the segments below is a secant?

a. (overline{ab})
b. (overline{cd})
c. (overline{ao})
d. (overline{bc})

Explanation:

A secant is a line that intersects a circle at two points. Let's analyze each option:

• $\overline{AB}$: Intersects the circle at only one point ($A$). So it is a tangent.
• $\overline{CD}$: Intersects the circle at only one point ($D$). So it is a tangent.
• $\overline{AO}$: Is a radius (connects the center $O$ to a point $A$ on the circle).
• $\overline{BC}$: Intersects the circle at two points. So it is a secant.

Answer:

D. $\overline{BC}$
