Who says you can’t create curves with line segments? It’s fascinating to discover a curve formed from a series of straight line segments. Line designs utilize basic geometric forms, making curves out of segments. Order and symmetry are the basis of string art’s appeal. Elaborate designs can be created with geometric shapes, points, and colored string.
Line designs form a basis for mathematical understanding of geometric shapes and relationships of points, segments, and angles. Each of the line segments is really a tangent for each of the curves being formed. But because of what we focus on, we often see the curves. For example, some of the curves that can be created are circles, parabolas, ellipses, hyperbolas, spirals, and some less known curves called cardioids, limacons, and deltoids. Yet in each case they were created with angles of different sizes, regular and irregular polygons, and a lot of segments and points.
