FAQs on Examples: Symmetry & Lines of Symmetry- 2 Video Lecture - Mathematics (Maths) Class 7 (Old NCERT)

1. What is symmetry?

Ans. Symmetry refers to a balanced arrangement of objects, shapes, or patterns that can be divided into two equal halves. In other words, if a shape or object can be folded along a line and the two halves match perfectly, it is said to have symmetry.

2. What are the lines of symmetry?

Ans. Lines of symmetry are imaginary lines that divide a shape or object into two identical halves. These lines can be vertical, horizontal, or diagonal, depending on the shape's characteristics. A shape can have multiple lines of symmetry, or it may not have any.

3. How can we determine the lines of symmetry in a shape?

Ans. To determine the lines of symmetry in a shape, we need to identify the points or lines along which the shape can be folded to create two identical halves. One way to do this is by visualizing and drawing lines on the shape to see if the halves match. Alternatively, if the shape has regular patterns or sides, we can use symmetry rules specific to those shapes to determine the lines of symmetry.

4. Can all shapes have lines of symmetry?

Ans. No, not all shapes have lines of symmetry. Shapes like circles and irregular polygons do not have any lines of symmetry. However, regular polygons like squares, rectangles, and equilateral triangles have multiple lines of symmetry. The presence of lines of symmetry depends on the shape's properties and structure.

5. Why is symmetry important in mathematics and design?

Ans. Symmetry plays a crucial role in mathematics and design because it represents balance, harmony, and aesthetic appeal. In mathematics, symmetry helps in solving problems related to geometry, algebra, and even number patterns. In design, symmetry is often used to create visually pleasing and balanced compositions in architecture, art, and other creative fields.
