Overview

A circle is a simple closed curve in which all points on its boundary are at the same distance from a fixed point inside it called the centre. This chapter introduces Class 6 students to the basic parts of a circle such as radius, diameter, chord, arc, sector, segment, tangent, and secant. Understan

Key Concepts

A circle is a closed curve

A circle is a closed curve where all points on the boundary (circumference) are equidistant from a fixed point called the centre.

The radius is the distance from

The radius is the distance from the centre to any point on the circle. The diameter is a line passing through the centre with endpoints on the circle.

A chord joins two points on

A chord joins two points on the circle. A secant cuts the circle at two points. A tangent touches the circle at exactly one point.

An arc is a part

An arc is a part of the circumference. A sector is the area between two radii and an arc. A segment is the area between a chord and an arc.

Learning Objectives

  • Define a circle and identify its centre and radius.
  • Understand and differentiate between radius, diameter, chord, and circumference.
  • Recognize the relationship between radius and diameter.
  • Identify and describe parts of a circle such as arc, sector, segment, tangent, and secant.
  • Distinguish between the interior, exterior, and points on a circle.
