Explanation
Line symmetry occurs when a shape can be folded so both halves match. Rotational symmetry occurs when a shape looks the same after rotation. Many shapes in nature have symmetry. Humans have approximate bilateral symmetry. Symmetry is important in art, design, and mathematics. Understanding symmetry helps analyze geometric properties.
Example
A butterfly has bilateral symmetry with identical left and right sides.
Frequently Asked Questions
What is the difference between line and rotational symmetry?
