Drawing of a zigzag.

A zigzag is a pattern made up of small corners at variable angles, though constant within the zigzag, tracing a path between two parallel lines; it can be described as both jagged and fairly regular.

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.

Although the origin of the word is unclear, its first printed appearances were in French-language books and ephemera of the late 17th century.[1]
