Rectilinear plane figures {polyomino} can involve congruent squares that share sides. Finite numbers of identical squares can join at edges to make shapes, such as crosses or lines. One polyomino can tile plane periodically or not. One polyomino cannot tile plane aperiodically. Polyomino pairs or triples can tile plane periodically, aperiodically, or not. Because aperiodic tilings are possible, no algorithm can decide, for all sets, if a polygon set will tile plane.
