What's the Difference Between a Circle and a Sector in Geometry?
This topic is relevant for:
A circle is a continuous curved shape with no beginning or end, consisting of all points that are equidistant from a central point called the center. On the other hand, a sector is a part of a circle enclosed by two radii (lines extending from the center to the edge of the circle) and an arc (a portion of the circle's circumference). Think of a pizza cut into equal-sized slices – each slice represents a sector of the circle.
