Infinite lines are lines that extend endlessly in both directions without any end points. They are straight and have no curvature. Infinite lines are often represented by arrows on both ends to indicate their unending nature. They do not have a fixed length or specific starting or ending point.
In Class 6 Maths Chapter 9 on Symmetry students learn about the concept of symmetry where a figure is divided into two identical halves by a line called the line of symmetry. The chapter covers different types of symmetry like reflection symmetry and rotational symmetry along with examples and applications in real life.
A circle has infinite lines of symmetry. Every diameter of a circle divides it into two equal halves and acts as a line of symmetry. Therefore a circle can be reflected across any line passing through its center.
