Question

which of the lines or segments be of circle o? answer

Explanation:

Step1: Recall the definition of a chord

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

Step2: Analyze each option

• $\overleftrightarrow{US}$: It is a line (not a segment), so it is not a chord.
• $\overline{TU}$: Both \(T\) and \(U\) are on the circle \(O\), so it is a chord.
• $\overline{KO}$: \(O\) is the center (not on the circle), so it is not a chord.
• $\overleftrightarrow{TR}$: It is a line (not a segment), so it is not a chord.

Answer:

\(\overline{TU}\)
