《新课程标准》指出:“数学作为一种普遍适用的技术,有助于人们收集、整理、描述信息,建立数学模型,进而解决数学问题,直接为社会创造价值”.数学建模思想是一种非常重要的数学思想.而解直角三角形应用题作为考查应用能力的题目一直是中考的热点.这类题目都可以通过建立梯形、三角形等模型,运用梯形、三角形的相关知识理解题目给出的示意图或自己画出示意图,找出要解的直角三角形,或
The New Curriculum Standard states: “Mathematics as a universal technique helps people gather, organize, describe information, build mathematical models, solve mathematical problems, and create value directly for society.” Mathematical Modeling Thought Is a very important mathematical thought.However, the problem of solving right angle triangle application problem as a test application ability has always been a hot spot in the senior high school entrance examination.These problems can be solved by building trapezoid, triangle and other models, using the knowledge of trapezoid and triangle Draw a sketch or draw your own schematic to find the right triangle to solve, or
