Rotational symmetry occurs when a shape looks identical after being rotated around a central point by a specific angle. In contrast, reflection symmetry involves mirror-image halves divided by a line of symmetry.

class 6 Mathematics Textbook Chapter 9 question answer
Rotational symmetry is distinguished from reflection symmetry by its focus on rotation. A shape with rotational symmetry looks identical after being rotated by specific angles around a central point. For example, a square has rotational symmetry at 90°, 180°, and 270°. Reflection symmetry, on the other hand, involves dividing a shape into two mirror-image halves by a line of symmetry. While reflection symmetry involves folding, rotational symmetry is about how a shape aligns during rotation.
