NCERT Solutions for Class 6 Math Chapter 13: Symmetry

The chapter will aid the students in learning about the symmetry observed in the figure they see around themselves. Certain figures with evenly balanced proportions are said to be symmetrical. Understanding the basics of symmetry helps students understand the figures and their construction in a better way. A figure has line symmetry only if a line can be drawn through the figure which divides into two identical parts. In such a case this line through the is called a line of symmetry. Line symmetry and mirror reflection are naturally related and linked to each other. A figure may have no line of symmetry such as a scalene triangle, only one line of symmetry such as an isosceles triangle, two lines of symmetry such as a rectangle or three lines of symmetry like an equilateral triangle. Even some alphabets in English show symmetry. It is important to intrigue young minds to think of such shapes. Application of symmetry is interesting, and students through the application of symmetry in Kaleidoscope or rangoli patterns drawn on any festival in our country can have a hands-on grasp on the subject matter. Observing such shapes, the students develop their cognitive skills and become more aware of the thing around them, what shape they are and why they are shaped the way they are. The following are the new terms associated with the chapter of symmetry:

• Symmetry
• Reflection
• Basics of symmetry
• Reflectional symmetry
