In geometry, an object has symmetry if there is an operation or transformation (such as translation, scaling, rotation or reflection) that maps the figure/object onto itself (i.e., the object has an invariance under the transform). Thus, a symmetry can be thought of as an immunity to change. For instance, a circle … See more The most common group of transforms applied to objects are termed the Euclidean group of "isometries", which are distance-preserving transformations in space commonly referred to as two-dimensional or three-dimensional … See more Reflection symmetry can be generalized to other isometries of m-dimensional space which are involutions, such as (x1, ..., xm) ↦ (−x1, ..., −xk, xk+1, ..., xm) in a certain system of Cartesian coordinates. This reflects the space along an (m−k)-dimensional See more Translational symmetry leaves an object invariant under a discrete or continuous group of translations $${\displaystyle \scriptstyle T_{a}(p)\;=\;p\,+\,a}$$. The illustration on the right shows four congruent footprints generated by translations along … See more Reflectional symmetry, linear symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection. See more Rotational symmetry is symmetry with respect to some or all rotations in m-dimensional Euclidean space. Rotations are direct isometries, which are isometries that preserve orientation. Therefore, a symmetry group of rotational symmetry is a subgroup of the … See more In 2D, a glide reflection symmetry (also called a glide plane symmetry in 3D, and a transflection in general) means that a reflection in a line or … See more In 3D geometry and higher, a screw axis (or rotary translation) is a combination of a rotation and a translation along the rotation axis. Helical symmetry … See more WebThe five symmetry elements have associated with them five types of symmetry operation, which leave the geometry of the molecule indistinguishable from the starting geometry.They are sometimes distinguished from symmetry elements by a caret or circumflex.Thus, Ĉ n is the rotation of a molecule around an axis and Ê is the identity operation.
