Polygonal chain

（重定向自Polygonal curve）

A set of n=17 points has a polygonal path with 4 same-sign slopes

In geometry, a polygonal chain is a connected series of line segments. More formally, a polygonal chain P is a curve specified by a sequence of points $\scriptstyle(A_1, A_2, \dots, A_n)$ called its vertices. The curve itself consists of the line segments connecting the consecutive vertices. A polygonal chain may also be called a polygonal curve, polygonal path, polyline, piecewise linear curve, or, in geographic information systems, a linestring or linear ring.
