*Q2. *

*Draw the line of symmetry.*

*Ans:*

- l
_{1 }is the line of symmetry. - l
_{1 }is the line of symmetry. - l
_{1}is the line of symmetry. - No line of symmetry.

In the symmetry chapter of class 6 NCERT maths book, students get to know what symmetry is what applications it has on the day to day life. Apart from that, different terminologies are discussed which include the line of symmetry, reflection, application of reflectional symmetry, etc.

NCERT has also included several activities in this chapter which can help the students to have a proper understanding of the different concepts taught in this chapter. Also, several practice questions are included in this chapter. It is advised that all the question from this chapter should be solved and the solutions should be properly understood to be able to have a better understanding of the concepts.
