From the point of view of symmetry, a regular zigzag can be generated from a simple motif like a line segment by repeated application of a glide reflection:
- /\/\/\/\/\/\/\/\/\
Equally it is the juxtaposition of chevrons.
A car, for example, could move in a zigzag, that is, not going straight, but instead moving left and right and left and so on. The trace of a triangle wave or a sawtooth wave could be described as a zigzag. Pinking shears are designed to cut cloth with a zigzag edge, to lessen fraying. Zigzags are a basic decorative pattern used on pottery.
