A **cissoid** is a type of curve that is defined in relation to a specific geometric construct. It is typically formed as the locus of points in a plane based on a particular relationship to a predefined curve, often involving circles or lines. The term "cissoid" is derived from the Greek word for "ivy," as some versions of these curves resemble the shape of ivy leaves.
