A chord is a line segment connecting two points on a circle's circumference but does not necessarily pass through the center. A radius is a line segment from the center of the circle to any point on its circumference. Therefore, every radius is half the diameter, while a chord can vary in length depending on its position.

FAQs & Answers

  1. What is a chord in geometry? A chord is a line segment that connects two points on a circle's circumference.
  2. How is a radius defined? A radius is a line segment from the center of a circle to any point on its circumference.
  3. Can a chord pass through the center of the circle? Yes, if a chord passes through the center, it is called a diameter.
  4. What is the relationship between radius and diameter? The radius is half the length of the diameter of a circle.
