• You can draw a wallpaper pattern by repeating a basic design element at regular intervals to the left and right of the original. Wallpaper Pattern

• Making a strip pattern or wallpaper design requires a series of “draw & move” steps. • You draw a basic design element. Then, you slide your pencil to a new position and repeat the element. • You slide in the same way to a new position and repeat the element again, and so on. • The slide movements from one position to the next are called… Translations.

• A design has translation symmetry if you can slide the whole design to a position in which it looks exactly the same as it did in its original position. • To describe translation symmetry, you need to specify the distance and direction of the translation. • An arrow can show the slide.
