Symmetry mainly adds importance to various architectural structures that we come across in our daily lives. Monuments like Thiruvannamalai 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 13.1 of Chapter 13.
