Study Notes
Symmetry and Chirality
- A plane of symmetry is a plane that divides an object into two symmetrical halves.
- Examples of objects with a plane of symmetry include:
- A person
- A hat
- A butterfly
- A person's hand or gloves
- An object without a plane of symmetry is called chiral, dissymmetric, or asymmetric.
Chirality
- A chiral object cannot be superimposed on its mirror image.
- Example of a chiral object: a left hand.
