关于解斜三角形的三角函数实际问题是近几年中考试题中频频出现了一类问题,解决这类问题的关键是运用“化斜为直”的数学思想方法,即将斜三角形通过添作高线化归为直角三角形,进而应用解直角三角形的知识解决问题.现例举中考题加以归类浅析,希望对同学们有所帮助. The practical problem of solving the trigonometric function of beveled triangles is that a kind of question frequently appears in the exam questions in recent years. The key to solve these problems is to use the mathematical method of " High-line into the right-angled triangle, and then use the knowledge of right-angle triangles to solve the problem.Examples to classify the test questions to be classified, I hope the students are helpful.
