We say that the figure f fits in the target t, or, equivalently, the target t covers the figure f, when there is a rigid motion ( an isometry of the plane ) so that ( f ) t, i. e., if t has a subset congruent to f. it might happen that a specific figure f and target t are given, and one wants to know if the figure fits in the target
如果t含有與f全等的子集，則稱f嵌人t或t覆蓋f對任意給定的f和t ，判定f是否嵌入t這類問題稱為嵌入問題給定一集族f和一目標集t ，尋找能覆蓋住f中任一元的t的最小相似圖形這類問題稱為覆蓋問題
