Domain Geometry. It only takes a minute to sign up. One way to replace a translation with two reflections is to first use a reflection to transform one vertex of the pre-image onto the corresponding vertex of the image, and then to use a second reflection to transform another vertex onto the image. Since every rotation in n dimensions is a composition of plane rotations about an n-2 dimensional axis, therefore any rotation in dimension n is a composition of a sequence of reflections through various hyperplanes (each of dimension n-1). Any translation can be replaced by two reflections. What is important to remember is that two lines of reflection that define a rotation can be replaced with any two lines going through the same intersection point and having the same angle.
