Understanding the Difference: Radius vs Chord of a Circle

Learn why a radius is not a chord in circle geometry with clear definitions and explanations.

285 views

A radius is not a chord of a circle because a chord is defined as a line segment with both endpoints on the circle’s boundary. A radius, however, extends from the circle’s center to its boundary, making it distinct from a chord. Understanding these definitions can help clarify various geometric concepts.

FAQs & Answers

  1. What is the definition of a chord in a circle? A chord is a line segment whose endpoints both lie on the boundary of the circle.
  2. Can a radius be considered a chord? No, a radius is not a chord as it connects the circle's center to a point on its boundary, unlike a chord.
  3. What are other parts of a circle? Besides chords and radii, a circle consists of diameter, circumference, arc, and sector.
