三角形【考点提要】以现实生活中的有关图形作为背景,通过不同的活动(观察、展开、折叠、变换、作图、推理等)探索相应的图形性质,这类考题是近年来的热点问题.另外还有运用三角形三边关系定理、内角和定理、等腰三角形定理和判定定理等解决实际问题等题型.对于识别图形和动手操作的考查,近年来也有所加强. The triangle “testpoint summary” uses the relevant graphics in real life as the background, and explores the corresponding graphic nature through different activities (observation, expansion, folding, transformation, graphing, reasoning, etc.). Such questions are hot topics in recent years. In addition, the use of triangular trilateral relations theorem, internal angles and theorems, isosceles triangle theorem and theorem to solve the actual problems and other questions type. For the identification of graphics and hands-on examination of the examination, in recent years has also been strengthened.
