NCERT Solutions Class 7 Maths Chapter 14 Exercise 14.2 Symmetry
Elaborating further on the topic of symmetry, the NCERT solutions for Class 7 maths Chapter 14 exercise 14.2 Symmetry explains how the shape and size of an object do not change when it is rotated, and the rotation of an object happens around a fixed point. The center of rotation is this fixed point. The angle of rotation is the angle of turning during rotation. A full turn entails a complete 360-degree revolution, while a half-turn is a 180-degree revolution, and a quarter-turn is a 90-degree rotation. For example, a windmill would not look symmetrical, but when rotated by 90-degrees, it would look the same hence it is said to have rotational symmetry. The NCERT solutions Class 7 maths Chapter 14 exercise 14.2 has 2 questions based on the above concept.
All the objects have rotational symmetry of order 1 because they possess the same position when rotated by 360 degrees. The Class 7 maths NCERT solutions Chapter 14 exercise 14.2 Symmetry can be downloaded from the link herewith :
