解斜三角形是解直角三角形的扩展部分,正弦定理和余弦定理是解斜三角形的重要依据.解三角形又常涉及到仰角、俯角、方位角等测量专用名称,它们是解决航行、测量等实际问题的工具.解决好这类问题,首先要经过分析,抽象构造三角形,将实际问题中的长度、角作为三角形相应的边和角,再通过解斜三角形得到解决.在解题过程中常用到转化、划归思想和方程思想.
The solution triangle is an extension of the solution triangle. The sine theorem and the cosine theorem are the important basis for solving the skew triangle. The solution triangle often involves special names such as elevation angle, depression angle, and azimuth angle. They are practical problems to solve navigation and measurement. The tools. To solve this kind of problem, we must first analyze, abstractly construct the triangle, and use the length and angle of the actual problem as the corresponding edges and angles of the triangle. Then we solve the problem by solving the oblique triangle. , classified as thinking and equations.
