Which term describes a segment whose endpoints lie on a circle?

• A. Cantabile
• B. Chord progression
• C. Chord
• D. Chorale

Answer: (C)

In geometry, a straight line segment whose endpoints lie on a circle is called a chord. That exactly describes the described segment, since both ends sit on the circle. A diameter is a special case of a chord that passes through the circle’s center and is the longest possible chord. The other terms—cantabile, chord progression, chorale—are musical terms and don’t describe a geometric segment on a circle.
