Yes, a chord is a line segment with endpoints on the circumference of the circle. If you can give more details on the problem, perhaps we can help more.
Do chords have to be line segments? And if so, are the endpoints on the circumference of the circle? I'm asking this b/c for a problem I'm given that EF and GH are chords of a circle. I have coords for F and G so I'm thinking that i connect those to make another chord.
