在正方形的网格中,每个小正方形的边长都是相等的,每个小正方形的顶点叫做格点(其他正多边形也有类似的情形),我们把以格点的连线为边的图形叫格点图形.近年来各地的中考试卷中频频出现这类与格点有关的数学问题,由于这类与网格有关的中考题大部分具有开放性,设计又新颖,能很好地考查学生的思维水平和思维能力,故很受命题者的青睐.但课本、作业本中这类问题的例题和习题却并不多见,在此,特作梳理,与大家一起赏析. In a square grid, the length of each small square is equal, and the vertices of each small square are called grids (for other regular polygons there are similar cases). In recent years, frequently appeared in the middle of the examination papers around the lattice-related mathematical problems, because most of these grid-related senior high school entrance examination questions are open, designed and novel, can well examine the students The level of thinking and thinking skills, it is very popular with the proponents of the However, textbooks, homework examples of such problems and exercises are rare, here, special combing, with everyone appreciation.
