Composition of Transformations
A composition of transformations is a combination of two or more transformations, each performed on the previous image. A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines).

A composition of reflections over intersecting lines is the same as a rotation (twice the measure of the angle formed by the lines). The composite of two translations across intersecting lines is equivalent to a rotation. The concepts is demonstration visually, and it is shown how to calculate the magnitude of the rotation.
