A line spiral is a spiral composed of right lines.
We distinguish the following forms:
- rectangular Archimedes' spiral
This spiral is the rectangular form of the Archimedes' spiral.
The distance between the windings is the same.
- rectangular equiangular spiral
Construct line pieces rectangular on each other, where the length is a factor a < 1 smaller than the former.
- right equiangular spiral
This curve approximates the equiangular spiral.
