The quadratrix, also known as the quadratrix of Hippias, is a curve used in mathematics, particularly in geometry. Specifically, it is a regular curve traced out by a line segment whose length is proportional to the angle it has rotated through; as the line turns, the length of the segment being traced is proportional to the angle of rotation through which it has rotated.<br><br>Another name for the curve is the spiral of Archimedes, although it is distinct from the more well-known example of the spiral with the same name that is now usually referred to as Archimedes' spiral.
