A glide-reflection is an isometry that is the product of a reflection and a translation in the direction of the axis of the reflection. ... Every isometry of the plane, other than the identity, is either a translation, a rotation, a reflection, or a glide-reflection.

Is a glide reflection A transformation?

A glide reflection is a composition of transformations.In a glide reflection, a translation is first performed on the figure, then it is reflected over a line. Therefore, the only required information is the translation rule and a line to reflect over. A common example of glide reflections is footsteps in the sand.

Are reflections Isometries?

A reflection is called a rigid transformation or isometry because the image is the same size and shape as the pre-image.
