| The Conchoid of Nicomedes is the conchoid of a straight line with respect to a point not on the line. |
| Nicomedes is famous for his treatise On conchoid lines which contain his discovery of the curve known as the conchoid of Nicomedes. |
| The ruler has a fixed distance marked on it and one mark is kept on a given line while the other traces the conchoid curve. |
| One of the best choices is the conchoid, according to Newton the simplest curve after the circle. |
| The conchoid has been employed by later mathematicians, notably Sir Isaac Newton, in the construction of various cubic curves. |
| Pappus tells us about the conchoid of Nicomedes in his Mathematical collection. |
