A Glide reflection is a transformation involving a translation and a reflection in a line parallel to the translation. Some strip patterns (on belts or wallpaper borders) are based on glide reflections. A glide reflection is a type of isometry of the Euclidean plane: the combination of a reflection in a line and a translation along that line. Reversing the order of combining gives the same result. The combination of a reflection in a line and a translation in a perpendicular direction is a reflection in a parallel line.
You may also apply this rule to negative angles (clockwise). A glide reflection is the composition of a reflection and a translation, where the line of reflection, m, is parallel to the directional vector line, v, of the translation. Example: A glide reflection is commutative.
