FAQs on Visual Worksheet: Symmetry - Mathematics (Maths) Class 7 (Old NCERT)

1. What is symmetry in geometry?
Ans.Symmetry in geometry refers to a balanced and proportional arrangement of parts on opposite sides of a dividing line or around a center point. An object is considered symmetrical if it can be divided into two or more identical parts that mirror each other.
2. How can I identify lines of symmetry in shapes?
Ans.To identify lines of symmetry in shapes, you can fold the shape along a line to see if both halves match perfectly. You can also use a mirror to check if one side reflects the other accurately. Common shapes like squares and circles have multiple lines of symmetry.
3. What are the different types of symmetry?
Ans.The different types of symmetry include reflective symmetry (where one half is a mirror image of the other), rotational symmetry (where the object can be rotated around a center point and appear the same), and translational symmetry (where a pattern can be repeated in a specific direction).
4. How is symmetry applied in real life?
Ans.Symmetry is applied in various fields such as architecture, art, nature, and design. For example, buildings often use symmetrical designs for aesthetic appeal, while artists might use symmetry to create balanced compositions. In nature, many flowers and animals exhibit symmetry as a form of beauty and functionality.
5. Can you provide examples of symmetrical shapes?
Ans.Examples of symmetrical shapes include a square, rectangle, circle, and equilateral triangle. Each of these shapes has specific lines of symmetry; for instance, a square has four lines of symmetry, while a circle has infinite lines of symmetry.
