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. Depending on context, we may consider a simple reflection (without translation) as a special case where the translation vector is the zero vector.

Famous quotes containing the words glide and/or reflection:
“Our life is not so much threatened as our perception. Ghostlike we glide through nature, and should not know our place again.”
—Ralph Waldo Emerson (1803–1882)
“Uncertainty about the outcome is a given in child rearing and not a reflection of a mother’s inadequacy. She should not be misled by her wish to be omnipotent, all-powerful, all-giving, the perfect mother, who will right all the wrongs and make up for all the deprivations of her own childhood. She is simply an imperfect human being with needs of her own.”
—Elaine Heffner (20th century)
