测量底部直接可以到达的物体的高度,就是解直角三角形问题,比较简单,在初中数学中已有详细介绍,这里不再赘述.下面举例说明测量底部不能直接到达的物体的高度.测量底部不能直接到达的物体的高度,不仅要解直角三角形,还要解斜三角形,通常有下面两种测量方法.方法1如图1,被测物体 The height of the object that can be reached directly at the bottom of the measurement is the problem of solving the right triangle. It is relatively simple. It has been introduced in detail in the junior high school mathematics and will not be described here. The following example illustrates the height of the object that cannot be reached directly at the bottom of the measurement. The bottom of the measurement cannot be directly The height of the object reached, not only to solve the right triangle, but also to solve the oblique triangle, usually the following two methods of measurement. Method 1 in Figure 1, the measured object
