In geometry, a point reflection (also called a point inversion or central inversion) is a transformation of affine space in which every point is reflected across a specific fixed point. When dealing with crystal structures and in the physical sciences the terms inversion symmetry, inversion center or centrosymmetric are more commonly used.

In mathematics, a reflection (also spelled reflexion) [1] is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is called the axis (in dimension 2) or plane (in dimension 3) of reflection. The image of a figure by a reflection is its mirror image in the axis or plane of reflection.
Key Terms. reflection: the property of a propagated wave being thrown back from a surface (such as a mirror) refraction: Changing of a light ray’s direction when it passes through variations in matter. index of refraction: For a material, the ratio of the speed of light in vacuum to that in the material.
And the same rules apply. The diagram below uses the point $$(1,2)$$ as the point of reflection. The the distances between each point on the preimage and the point of reflection $$ (1,2)$$ are equal to the distances between $$(1,2)$$ and each point on the image
