勾股定理大家都非常熟悉,其定义是:“两个直角边的平方和等于斜边的平方。”勾股定理在施工放线中运用很广,特别是在一些小建筑。例:小商店,值班室,农村住房等。在施工放线时,既不要使用经纬仪等仪器,又能节时、省工,为施工人员所喜爱。具体方法是:定一墙角为一点,以此一点分别在纵横方向量取3个单位(例:3m或4个单位(例:4m)再在纵横3或4单位处定两点,如果此二点间距离等于5个单
The Pythagorean theorem is very familiar to everyone and its definition is: “The sum of the squares of two right-angled edges is equal to the square of the hypotenuse.” The Pythagorean Theorem is widely used in the construction of a line, especially in some small buildings. Examples: small shops, duty rooms, rural housing, etc. In the course of laying out the line, neither theodolites nor other instruments, but also time-saving, labor saving, are favored by construction workers. The specific method is: set a corner to a point, in this way, measure 3 units in vertical and horizontal directions (example: 3m or 4 units (eg 4m) and then set 2 points in vertical and horizontal 3 or 4 units, if The distance between points is equal to 5 singles
