What is a chord of a circle?

A chord in a circle is a straight line segment that connects any two points on the circle's circumference (edge). It can be of any length, but the longest possible chord is the diameter, which is a special chord that passes through the center of the circle.

What is a sector of a circle?

A sector of a circle is like a slice of pie or pizza, a portion of the circle enclosed by two radii (lines from the center to the edge) and the arc (the curved edge) connecting their endpoints, defined by a central angle.

What is a segment of a circle?

A segment of a circle is the region or area enclosed by a chord (a straight line connecting two points on the circle) and the arc (the curved part of the circle's edge) between those two points, essentially a "slice" cut off by a straight line
