Question

question 4 of 25
which line segment is a chord of ⊙e in the diagram below?

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

Explanation:

A chord of a circle is a line segment with both endpoints on the circle.

• $\overline{BC}$ has one endpoint outside the circle, so it is not a chord.
• $\overline{AB}$ has one endpoint outside the circle, so it is not a chord.
• $\overline{CD}$ has both endpoints on $\odot E$, so it is a chord.
• $\overline{DE}$ is a radius, with one endpoint at the center, so it is not a chord.

Answer:

C. $\overline{CD}$
