摘要
根据解析法计算图形面积的特点,对图形顶点的2种不同方向编号、4种不同计算公式进行了探讨,得出利用测量坐标计算图形面积与图形顶点编号方向无关,与坐标增减规律无关的结论。
According to the characteristic of area calculating formulas.with analytical method, this paper discusses the numbering of two differ- ent directions of the figure vertex and four different calculating formulas, and concludes that the calculation of a figure area with survey coordi- nates has nothing to do with either the direction of figure vertex numbering or the coordinates＇ fluctuation.
