Unit 3.7 - Glide Planes and Wallpaper Groups

Unit 3.7 of our course The Fascination of Crystals and Symmetry Additonal resources at: https://crystalsymmetry.wordpress.com... In this unit we want to look at glide planes, one of the hree symmetry elements, which have a translational component. In the plane, i.e. in 2D objects these kind of symmetry elements are caled glide lines. Furthermore, we will explore the 5 Bravais lattices of the plane and the 17 plane symmetry groups, which describe the symmetry of 2D pattern completely.
