define "chords" in a mathematical sense

In mathematics, "chords" typically refer to a line segment that connects two points on a curve, but does not necessarily pass through the center. The concept of chords is commonly used in the context of circles and curves. Within this context, a chord is simply a straight line segment whose endpoints lie on the curve. Chords can be described using various properties, such as length, position, or angle subtended at the center of the curve. Understanding chords is essential in studying geometric properties and relationships of circles and curves.

In a simpler sense, "chords" in mathematics are like straight lines that connect two points on a curve, such as a circle. The chord doesn't have to go through the center of the curve. It's like drawing a straight line between two points on a curved shape. Chords are important to understand the properties and relationships of curves and circles.
