The biggest chord of the circle is called the diameter. It is the longest line segment that can be drawn within the circle, passing through the center and touching the circle at two points directly opposite each other. The diameter divides the circle into two equal halves.

FAQs & Answers

  1. What is the formula to calculate the diameter of a circle? The diameter can be calculated by doubling the radius: Diameter = 2 × Radius.
  2. How is a chord different from a diameter? A chord is any line segment that connects any two points on the circle, while the diameter is the longest chord that passes through the center.
  3. Why is the diameter important in geometry? The diameter is crucial in geometry as it helps define the size of a circle and serves as a basis for calculating circumference and area.
