NCERT Solutions for Class 6th Maths Chapter 13 Symmetry Exercise 13.3 deals with questions related to the making of symmetrical figures. Symmetry mainly adds importance to various architectural structures that we come across in our daily lives. Monuments like Tiruvannamalai temple in Tamil Nadu and Taj Mahal in Agra help us understand the concept of symmetry in a better way. Making of symmetrical figures is the main concept which is discussed under Exercise 13.3 of Chapter 13.
