The NCERT Book for Class 7 Maths Chapter 12: Symmetry is a comprehensive resource that introduces students to the concept of symmetry in geometry. This chapter aims to develop students’ understanding of different types of symmetry and their applications.
The chapter begins by defining symmetry and explaining its importance in various objects and shapes. Students learn about the line of symmetry and explore different types of symmetry, such as bilateral symmetry and rotational symmetry.
Furthermore, the chapter covers the concept of reflection symmetry, where objects can be divided into two equal halves through a line of symmetry. Students learn how to identify and draw symmetrical figures using reflection.
The chapter also explores rotational symmetry, where objects can be rotated by certain angles and still retain their original shape. Students learn how to identify and create figures with rotational symmetry.
Students are exposed to various examples of symmetrical objects and patterns in their surroundings, helping them understand the practical applications of symmetry.
The NCERT Book for Class 7 Maths Chapter 12 provides numerous examples, exercises, and practice problems to reinforce the concepts learned. It encourages students to think creatively and apply their knowledge of symmetry in identifying and creating symmetrical figures. The book is available in PDF format, allowing students to access it conveniently and enhance their understanding of symmetry.
