Question

1. which choice is chord?

options:

• $overline{lg}$
• $overline{cj}$
• $overline{ch}$
• $overline{lm}$

Explanation:

Step1: Recall the definition of a chord

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

Step2: Analyze each option

• For $\overline{LG}$: Both endpoints \( L \) and \( G \) lie on the circle, so it is a chord.
• For $\overline{CJ}$: Point \( C \) is the center (not on the circle), so it is a radius, not a chord.
• For $\overline{CH}$: Point \( C \) is the center (not on the circle), so it is a radius, not a chord.
• For $\overline{LM}$: Point \( M \) is outside the circle, so it is not a chord.

Answer:

$\boldsymbol{\overline{LG}}$ (A. $\overline{LG}$)
