What is another word for segment of a circle?
Pronunciation: [sˈɛɡmənt əvə sˈɜːkə͡l] (IPA) 
A segment of a circle is a portion of the circle that is cut off by a chord. This region is often referred to as a circular sector, arc, or wedge. A sector is a region of the circle that is bounded by two radii and an arc, while an arc is a part of the circumference of a circle. A wedge, on the other hand, is a portion of a circular sector that lies between two radii and the arc. Another synonym for the segment of a circle is a slice where the circle is cut and separated by a line, forming a portion of a circle. These terms are commonly used in geometry and trigonometry when discussing circular shapes.
