Which term describes the part of a circle between two sides of a central angle that measures more than 180°?
A. Major arc
B. Minor arc
C. Chord
D. Semicircle
Answer (1)
A major arc is an arc with a measure greater than 180 degrees.
A minor arc is an arc with a measure less than 180 degrees.
A chord is a line segment connecting two points on a circle.
A semicircle is an arc with a measure of 180 degrees. The correct answer is A .
Explanation
Analyze the options Let's analyze the options:
Major arc: An arc of a circle with a measure greater than 180 degrees.
Minor arc: An arc of a circle with a measure less than 180 degrees.
Chord: A line segment connecting two points on a circle.
Semicircle: An arc of a circle with a measure of exactly 180 degrees.
The question asks for the term that describes the part of a circle between two sides of a central angle that measures more than 180 degrees. Based on the definitions, the correct term is a major arc.
Determine the correct term The term that describes the part of a circle between two sides of a central angle that measures more than 180 degrees is a major arc .
Examples
Imagine you're cutting a pizza. If you cut out a slice that's more than half the pizza, the crust along that slice represents a major arc. Major arcs are useful in various fields, such as architecture and engineering, where understanding circular segments is crucial for design and construction.
