Question

what does (overleftrightarrow{cde}) describe? a minor arc a major arc a semicircle a chord

Explanation:

Step1: Recall definitions

• Minor arc: An arc that is less than a semicircle.
• Major arc: An arc that is greater than a semicircle.
• Semicircle: An arc that is exactly half of a circle.
• Chord: A straight - line segment whose endpoints lie on the circle.

Step2: Analyze \(\overparen{CDE}\)

Since \(\overparen{CDE}\) is more than half of the circle (a semicircle is half of the circle), it is a major arc.

Answer:

a major arc
