Some chiral three-dimensional objects, such as the [[helix]], can be assigned a right or left [[handedness]], according to the [[right-hand rule]].

Many other familiar objects exhibit the same chiral symmetry of the human body, such as gloves and shoes. Right shoes differ from left shoes only by being mirror images of each other. In contrast thin gloves may not be considered chiral if you can wear them [[wiktionary:inside out|inside-out]].<ref>{{cite journal

The J-, L-, S- and Z-shaped ''[[tetromino]]es'' of the popular video game [[Tetris]] also exhibit chirality, but only in a two-dimensional space. Individually they contain no mirror symmetry in the plane.
