勾股定理实际上描述了一个从形到数的过程,因此,勾股定理是数形结合的典型载体.勾股定理的起点在形,落脚点在数,所以勾股定理的应用主要是用来解决数的问题,如求线段的长度、距离、路程、点的坐标、周长、面积等.下面,举例说明勾股定理的应用.一、解决有关距离的问题例1为了丰富少年儿童的业余生活,某社区要在如图1所示的AB所在的直线上建一座图书室. Pythagorean theorem actually describes a process from form to number, so the Pythagorean theorem is a typical carrier of the combination of number and form. Pythagorean theorem has its starting point in form and end point, so the application of the Pythagorean theorem mainly uses To solve the number of problems, such as the length of the line segment, distance, distance, point coordinates, perimeter, area, etc. Below, an example of the application of the Pythagorean Theorem 1. First, to solve the problem of distance Example 1 In order to enrich the children’s Amateur life, a community to be located in the AB shown in Figure 1 where a straight line to build a library.
