== == Headline text == == {{otheruses|Zig zag}} A '''zigzag''' is a [[pattern]] made up of many small corners at an [[angle|acute angle]], 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]]. Equally it is the [[juxtaposition]] of [[chevron (insignia)|chevron]]s, or of [[forward slash]]es and [[backslash]]es: :<tt>/\/\/\/\/\/\/\/\/\</tt> [[Lightning]] is often drawn as a zigzag, with long downward strokes and short backward ones. Stores of the defunct U.S. retail chain [[The Treasury (retailer)|The Treasury]] (also [[Treasure Island (retailer)|Treasure Island]]) each had a distinct zigzag roof, many of which still survive on reused buildings nearly three decades after the chain closed. The roof zigzag was also seen on the store [[logo]]. An automobile can move in a zigzag, that is, not going straight, but instead turning left and right and left repeatedly. In a city where streets are oriented toward the four [[cardinal direction]]s, this would be illustrated by, for example, driving north, west, north, west, north, west, and so on around the [[city block]]s, in order to go northwest. (This would not make the trip any shorter; however, it might avoid [[traffic]].) The [[trace]] of a [[triangle wave]] or a [[sawtooth wave]] is a zigzag. [[Pinking shears]] are designed to cut cloth or paper with a zigzag edge, to lessen fraying. Zigzags are a basic decorative pattern used on [[pottery]], and often for the cuts which separate [[ravioli]]. In [[sewing]], a '''zigzag stitch''' is a [[sewing machine|machine]] stitch in a zigzag pattern. Tightly spaced zigzag stitches are used to emulate [[embroidery stitch]]es such as satin stitch, and to reinforce [[buttonhole]]s. A zigzag stitch is also used as a non-structural seam, to temporarily hold two panels together edge-to-edge (and eliminate the ridge that would "x-ray" through). This is done when another panel will overlay the seam and provide support.
