几何图形边的关系在小学阶段,主要研究图形边的大小关系和位置关系。三角形是最简单的封闭图形,对三角形边的关系的探索,是小学研究几何图形边的大小关系的开始,是对三角形认识的一次升华,是从图形外部的整体感知到图形内部的内在规律的一次探索过程,是从图形要素的认识到要素之间关系的一次递进过程,是从直观观察到思想感悟的一次体验过程,它是将来学生进一步认识其他几何图形、探索
The relationship between the edge of the geometry In the elementary stage, the main study of the size of the relationship between the edge and location of graphics. Triangles are the simplest closed figures. The exploration of the relationship between triangle edges is the beginning of the study of the relationship between the size and the size of geometric shapes in primary schools. It is also a sublimation of the understanding of triangles and the intrinsic law of the interior of the graphs A process of exploration, from the understanding of the graphic elements to the relationship between the elements of a progressive process, is intuitive observation of the perception of an experience process, it is the future students to further understand other geometric shapes, to explore
