“解直角三角形”是探究直角三角形中边角关系的问题,是现实世界中应用广泛的关系之一.锐角三角函数在解决现实问题中有着重要的作用,如测量、建筑、工程技术和物理学中,人们常常遇到距离、高度、角度的计算问题.一般说来,这些实际问题的数量关系往往归结为解直角三角形中边角的关系问题.“解直角三角形”中的应用问题是近年各地中考的热点,这和“解直角三角形”知识与实际生活紧密相关分不开.解答这类问题,除 The solution of the right angle triangle is one of the most widely used relationships in the real world.Animal angle trigonometry plays an important role in solving practical problems such as measurement, architecture, engineering and engineering In physics, people often encounter the calculation of distance, height and angle.In general, the quantitative relationship between these practical problems often boils down to the relationship between the corners in a right-angled triangle. The problem is in recent years all over the examination hotspot, which and “solution right triangle ” closely related to knowledge and real life is inseparable.To answer such questions, except
