21. What is symmetry?

Ans.  Symmetry is a balanced arrangement of parts on either side of an axis or a center. If one part mirrors the other, it is symmetrical.


22. How do you identify the axis of symmetry in a shape?

Ans. The axis of symmetry is an imaginary line where a shape can be folded to create two identical halves. To find it, look for a line along which the shape's two halves match.


23. Can all shapes have symmetry?

Ans. No, not all shapes have symmetry. Only specific arrangements of lines, curves, or patterns result in symmetry. For example, a circle has infinite lines of symmetry, while irregular shapes may not have any.


24. Explain rotational symmetry?

Ans. Rotational symmetry is when a shape looks the same after a certain degree of rotation around its center. For instance, a square has rotational symmetry of 90 degrees, as it looks the same after a quarter turn.


25. How can symmetry be applied in real life?

Ans. Symmetry is seen in many everyday objects, from buildings to nature. Architects use symmetry in designing structures, and understanding symmetry helps artists create balanced and visually appealing artworks. Even in biology, living organisms often display symmetrical patterns.
