Helix A helix (pl: helixes or helices) is a type of smooth space curve, i.e. a curve in three-dimensional space. It has the property that the tangent line at any point makes a constant angle with a fixed line called the axis.Examples of helices are coil springs and the handrails of spiral staircases. double helix consists of two (typically congruent) helices with the same axis, differing by a translation along the axis. A conic helix may be defined as a spiral on a conic surface, with the distance to the apex an exponential function of the angle indicating direction from the axis.
