用形状相同或不同的平面封闭图形,把一块地面既无缝隙、又不重叠地全部覆盖,叫做平面镶嵌,也叫做密铺.在日常生活中,最常见的是正多边形的镶嵌.由于镶嵌的正多边形的边必与另一正多边形的边重合,所以镶嵌的正多边形的边都必须相等,且在每个顶点处镶嵌的各个正多边形的内角和为360°.我们关心的问题是选择什么样的正多边形才能镶嵌,现就几种类型分类探究如下,供同学们参考. With the same or different shape of the plane closed graphics, a piece of the ground without gaps, but not overlapping all covered, called Plane mosaic, also known as compact shop .In daily life, the most common is the regular polygon inlay. The edges of the polygon must coincide with the edges of another regular polygon, so the sides of the regular polygons must be equal and the interior angles of the respective regular polygons inlaid at each vertex sum to 360. The question we care about is what to choose Of regular polygons can be inlaid, now explore the following types of classification, for the students reference.
