A reflection is a flip of an object over a line. Let's look at two very common reflections: a horizontal reflection and a vertical reflection. Notice the colored vertices for each of the triangles. The line of reflection is equidistant from both red points, blue points, and green points.
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.
