NCERT Solutions For Class 7 Maths Chapter 14 Symmetry in Hindi - 2025-26
FAQs on NCERT Solutions For Class 7 Maths Chapter 14 Symmetry in Hindi - 2025-26
1. How do the NCERT Solutions for Class 7 Maths Chapter 14 help in mastering the concepts for the 2025-26 exams?
The NCERT Solutions for Class 7 Maths Chapter 14 provide step-by-step methods for solving every problem in the textbook. By following these solutions, students learn the correct methodology as per the CBSE guidelines. This ensures they not only find the right answer but also understand the logic behind identifying the line of symmetry and calculating the order of rotational symmetry, which is crucial for scoring well in exams.
2. What specific concepts are covered in the solutions for Exercise 14.1 of Chapter 14, Symmetry?
The NCERT Solutions for Exercise 14.1 focus primarily on line symmetry. The questions guide you on how to:
- Identify lines of symmetry in various geometrical figures.
- Draw the lines of symmetry for given shapes.
- Complete figures that are symmetrical along a given mirror line.
3. What is the step-by-step method to determine the order of rotational symmetry for a shape as explained in the NCERT Solutions?
The NCERT Solutions explain a clear, step-by-step method:
1. First, identify the centre of rotation, which is the fixed point around which the object turns.
2. Next, rotate the object clockwise or anti-clockwise by a certain angle.
3. Count how many times the object looks exactly the same as its original position during a full 360-degree rotation.
4. The total count is the order of rotational symmetry. For example, a square has an order of 4.
4. How many exercises are there in Chapter 14, and what does each one focus on?
Class 7 Maths Chapter 14, Symmetry, has three exercises in total. The NCERT Solutions provide detailed answers for all of them:
- Exercise 14.1: Focuses on identifying and drawing lines of symmetry.
- Exercise 14.2: Deals with rotational symmetry, including the centre and order of rotation.
- Exercise 14.3: Combines both concepts, exploring shapes that have both line and rotational symmetry.
5. Why is it important to follow the exact steps given in NCERT Solutions when identifying lines of symmetry for complex figures?
Following the exact steps is crucial because it ensures accuracy and prevents common errors. For complex figures, it's easy to miss a line of symmetry or imagine one that doesn't exist. The NCERT Solutions demonstrate a systematic approach, such as folding the shape mentally or drawing it on paper, to confirm that one half is the perfect mirror image of the other. This methodical process, as per the CBSE curriculum, guarantees you don't lose marks for incomplete or incorrect answers.
6. What is a common mistake students make when solving problems on rotational symmetry, and how do the NCERT Solutions help prevent it?
A common mistake is confusing the angle of rotation with the order of rotation. Students often write the angle (e.g., 90°) instead of the order (e.g., 4). The NCERT Solutions clearly differentiate between these two concepts. They show how to first find the smallest angle that makes the shape look the same and then use it to calculate the order (by dividing 360° by that angle), reinforcing the correct method.
7. How do the NCERT Solutions explain the relationship between line symmetry and rotational symmetry in regular polygons?
The NCERT Solutions clearly illustrate that for any regular polygon, the number of lines of symmetry is equal to its order of rotational symmetry. For instance, the solutions show that an equilateral triangle has 3 lines of symmetry and an order of rotational symmetry of 3. Similarly, a square has 4 lines of symmetry and an order of 4. This helps students understand the direct relationship between these two properties in symmetrical shapes.
