#### About Class 6 Maths Chapter 4

In 6 Maths Chapter 4 Basic Geometrical Ideas, we will study about the geometrical figures like Point, Line segment, Line, Intersecting lines, Parallel lines, Simple Curves, etc.
Circle: A closed curve which remains at constant distance from a point (its centre).
Sector: A region in the interior of a circle enclosed by an arc on one side and a pair of radii on the other two sides is called a sector.
Segment: A region in the interior of a circle enclosed by a chord and an arc is called a segment of the circle.
Circumference: The distance around a circle is its circumference.
Chord: A chord of a circle is a line segment joining any two points on the circle.
Diameter: A diameter is a chord passing through the centre of the circle.
The diameter of a circle divides it into two semi-circles.
A ray is a portion of line starting at a point and going in one direction endlessly whereas a line segment corresponds to the shortest distance between two points.
