In [[mathematics]], '''reflection symmetry''', '''line symmetry''', '''mirror symmetry''', or '''mirror-image symmetry''' is [[symmetry]] with respect to a [[Reflection (mathematics)|reflection]]. That is, a figure which does not change upon undergoing a reflection has reflectional symmetry.

In [[Two-dimensional space|2-dimensional space]], there is a line/axis of symmetry, in [[Three-dimensional space|3-dimensional space]], there is a [[plane (mathematics)|plane]] of symmetry. An object or figure which is indistinguishable from its transformed image is called [[mirror image|mirror symmetric]].
