Question

using the figure shown, which line segment could represent a chord of the circle?
options:
$overline{op}$
$overline{qr}$
$overline{oq}$
all of the above

Explanation:

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

• $\overline{OP}$ has one endpoint at the center $O$ and the other outside the circle, so it is not a chord.
• $\overline{OQ}$ has one endpoint at the center $O$ and the other on the circle, so it is a radius, not a chord.
• $\overline{QR}$ has both endpoints $Q$ and $R$ on the circle, so it fits the definition of a chord.

Answer:

$\overline{QR}$
