zigzag


Written By: Ehsan Jahandarpour

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. The origin of the word is unclear. Its first printed appearance was in French books in the late 17th century.
