Definition

A chord is a line segment with both endpoints on the circle.

Description

Chords are fundamental elements in the study of circles, representing line segments that connect two points on the circle's circumference. They are used in various real-world applications, such as in architecture and engineering, where chords can help in designing arches and bridges. Mathematically, the properties of chords are explored in the context of circle theorems, such as the perpendicular bisector of a chord passing through the circle's center. Understanding chords is crucial in math education as it enhances students' ability to analyze geometric shapes and solve problems involving circle properties, which are vital skills in advanced geometry and trigonometry.
