Concept of Symmetry in Class 6 Maths Chapter 9
Class 6 Maths Chapter 9 on Symmetry introduces students to the fundamental concepts of line symmetry, reflection symmetry and rotational symmetry. These concepts are frequently tested in multiple-choice questions as they form the basis of many geometrical principles. By studying symmetry, students develop the ability to visualize and identify symmetrical figures, which is an essential skill for solving MCQs quickly. NCERT Class 6 Maths Chapter 9 explains how to determine the number of lines of symmetry in various geometric shapes like squares, triangles and hexagons. This understanding is crucial when answering questions that ask about symmetrical properties or the effects of transformations on a shape.
Q1. What happens when a shape has both reflection and rotational symmetry?
Q2. How many lines of symmetry does a regular pentagon have?
Lines of Symmetry in Class 6th Mathematics Chapter 9
One of the most common types of MCQs related to symmetry involves identifying the number of lines of symmetry in given figures. NCERT Class 6 Maths Chapter 9 provides hands-on activities, such as folding paper and drawing lines, which help students recognize symmetrical patterns. MCQs may ask students to determine which figures have one, two or multiple lines of symmetry. By practicing the exercises given in the book, students can improve their ability to answer these questions quickly. The concept of mirror images, which is closely related to symmetry, is often tested in exams through reflection-based MCQs.
Q3. Which of the following figures has no line of symmetry?
Q4. What is symmetry?
Class 6 Maths Chapter 9 Rotational Symmetry
Another important concept covered in Class 6 Maths Chapter 9 is rotational symmetry, which refers to figures that look the same after being rotated by a certain angle. MCQs frequently test students on identifying shapes with rotational symmetry and calculating their angles of rotation. For example, students may be given a diagram of a windmill or a star and asked how many times it maps onto itself during a full rotation. Class 6 Mathematics NCERT Chapter 9 explains how to determine the smallest angle of rotation, a concept that is commonly used in competitive exams. Understanding rotational symmetry helps students solve these MCQs efficiently by recognizing repeating patterns.

Real-World Applications of Class 6 Maths Chapter 9 MCQs
Symmetry is not just a mathematical concept but also a principle found in nature and architecture. MCQs include real-life examples of symmetry, such as identifying symmetrical structures like the Taj Mahal, flowers or insects. NCERT Class 6 Maths Chapter 9 encourages students to observe symmetry in everyday life, which enhances their ability to answer application-based MCQs. Some questions might present a real-world object and ask students to determine whether it has line symmetry, rotational symmetry or both. This practical approach to symmetry makes it easier for students to understand its significance and apply it in different contexts.
Q7. How many lines of symmetry does a square have?
Q8. The order of rotational symmetry of an equilateral triangle is
Problem-Solving with Class 6 Maths Chapter 9 MCQs
Since MCQs require quick thinking and accuracy, Class 6 Mathematics Chapter 9 provides problem-solving strategies to identify symmetrical figures without extensive calculations. The math exercises help students recognize symmetrical patterns through observation and logical reasoning. Many exams include MCQs that test symmetry by asking students to complete a given pattern, determine missing symmetrical parts or identify incorrect symmetrical representations. By practicing these types of questions, students can develop a systematic approach to solving MCQs effectively. Mastering symmetry through Class 6 Math NCERT Chapter 9 ensures that students are well-prepared to tackle geometry-based multiple-choice questions in their exams.
Q9. A line that divides a figure into two equal mirror halves is called
Q10. What is the centre of rotation called in rotational symmetry?
What are the key topics covered in Class 6 Maths Chapter 9 Symmetry?
NCERT Class 6 Mathematics Chapter 9 Symmetry covers important concepts like line symmetry, reflection symmetry and rotational symmetry. It explains how to identify symmetrical figures, count lines of symmetry and determine angles of rotation. The chapter also includes practical activities like paper folding and real-world examples of symmetry in nature and architecture.
How is rotational symmetry different from line symmetry in Class 6 Maths Chapter 9?
In Class 6 Maths Chapter 9, line symmetry refers to a figure being divided into two equal mirror halves by a straight line, while rotational symmetry means a figure looks the same after being rotated by a certain angle. For example, a square has four lines of symmetry and rotational symmetry at 90°, 180° and 270°.
Why is Class 6 Maths Chapter 9 Symmetry important for MCQs?
Class 6 Maths Chapter 9 is important for MCQs as it helps students quickly identify symmetrical figures, count lines of symmetry and determine rotational angles. Many competitive exams include symmetry-based questions and understanding these concepts allows students to solve such problems efficiently and accurately.
