Noun

/ˈkɒŋ.kɔɪd/

/ˈkɑːn.kɔɪd/

Any of a family of plane curves generated from a fixed point, a straight line, and a constant distance, obtained by marking off the constant distance on the line from the point.

In analytic geometry, the conchoid is constructed by measuring a fixed distance from a given line along every ray issuing from a fixed point.

The conchoid of Nicomedes, a specific member of this family, historically used for trisecting angles and duplicating the cube.

Nicomedes devised the conchoid to solve classical problems such as the trisection of an angle.
