Rotational symmetry occurs when a shape looks identical after being rotated about a central point by a specific angle. It can be identified by rotating the shape and checking if it overlaps with itself.
Class 6 NCERT Ganita Prakash Chapter 9 Symmetry
class 6 Mathematics Textbook Chapter 9 question answer
Rotational symmetry is when a shape retains its appearance after being rotated around a central point by a certain angle. To identify this symmetry, rotate the shape step by step and check if it matches its original position at specific intervals. The smallest angle at which a shape appears identical is called the angle of symmetry. For example, a square has rotational symmetry at 90°, 180°, 270°, and 360°, as it matches its original orientation at those rotations.
