NCERT Solutions Class 7 Maths Chapter 14 Symmetry
The NCERT Solutions for Class 7 maths Chapter 14 Symmetry explains the concept of symmetry that is almost everywhere in our surroundings, in nature, and in real-life scenarios as well. Symmetric patterns are seen throughout nature, such as the growth and development of living organisms, flowers, trees, and leaves, as well as many other natural occurrences.
Symmetry can also be created in architecture, as well as art and music. Similarly, mathematics is also governed by certain symmetries or patterns that repeat themselves over and over again. These NCERT solutions Class 7 maths Chapter 14
starts with recalling the concept of line symmetry that means a line, over which if the figure is folded, its parts will coincide. This line of symmetry is also known as the axis.
The chapter talks about the symmetry of regular polygons. The students will discover interesting facts about them, including that the regular polygons have multiple lines of symmetry. More such facts can be read in the Class 7 maths NCERT solutions Class 7 maths Chapter 14 Symmetry, which is given below and also find some of these in the exercises given below.

- Class 7 Maths Chapter 14 Ex 14.3 - 7 Questions
Topics Covered: Line and Rotational symmetry, order of rotational symmetry, symmetry of regular polygons, terms like the center of rotation, angle of rotation, also, the two kinds of rotation like clockwise and anticlockwise have been covered in detail in the Class 7 maths NCERT solutions Chapter 14.
Total Questions: Class 7 Maths Chapter 14 Symmetry Chapter 14 has 19 questions in all, 12 of which are very easy, 4 involve drawing the figures in order to complete their symmetry, while the rest 3 can be classified as moderately difficult.
List of Formulas in NCERT Solutions Class 7 Maths Chapter 14
The concept of symmetry entails certain criteria to be fulfilled in order for a figure to be called symmetrical. The students need to have dedicated observational skills and focus, in order to analyze and categorize the given figure as symmetrical while applying the knowledge of these rules. Hence, these criteria or logics are important to remember. Some of them are given below.
- Lines of symmetry of Regular Polygon: A regular polygon’s lines of symmetry are as many as the number of its sides.
- Order of Rotational Symmetry: When an object takes a complete 360-degree turn, the number of times it looks the same is called the order of rotational symmetry. For example, for a square, it will be 4, whereas for a triangle it will be 3.

What are the Important Formulas in NCERT Solutions Class 7 Maths Chapter 14?
The topic of symmetry is based on the concept of balance which is central to the understanding of how things are ordered in time, space, and form. There are certain rules and logics related to symmetry, and if the object or figure follows these criteria, it can be termed symmetrical. Some of these criteria are as follows: A figure can be called symmetrical only if, when folded on its line of symmetry, both parts of its images coincide exactly. Also, if we take the case of regular polygons, which have equal sides, their lines of symmetry are as many in number as the number of sides that they possess.
How CBSE Students can utilize NCERT Solutions Class 7 Maths Chapter 14 effectively?
