In [[recreational mathematics]], a '''polyform''' is a [[plane (mathematics)|plane]] figure or solid compound constructed by joining together identical basic [[polygon]]s. The basic polygon is often (but not necessarily) a [[convex polygon|convex]] plane-filling polygon, such as a [[Square (geometry)|square]] or a [[triangle]]. More specific names have been given to polyforms resulting from specific basic polygons, as detailed in the table below. For example, a square basic polygon results in the well-known [[polyomino]]es.
