初中数学中全等三角形,其实是对平面几何中两个图形关系的研究。三角形的全等是两个形状、大小都相同的三角形,其中一个三角形可以经过平移、旋转、对称等运动与另一个三角形完全重合。三角形全等是两个三角形之间最常见的关系。在这一章的教学中,学生不仅要学会如何去识别全等三角形,还要让学生掌握其中的思维方式。利用初中生所特有的好奇心,激发学生对数学的学习兴趣。教师通过带领学生探索三角形全等的条件,让学生体会到分析问题、
Junior high school mathematics congruent triangle, in fact, is the plane geometry of the relationship between the two graphics. Triangle congruent is two triangles of the same shape and size. One of the triangles can be completely overlapped by another triangle by translation, rotation and symmetry. Triangle congruent is the most common relationship between two triangles. In this chapter, students not only learn how to recognize congruent triangles, but also let them master the way of thinking. Using the unique curiosity of junior high school students, to stimulate students interest in learning mathematics. Teachers by leading students to explore the equality of triangles conditions, so that students understand the analysis of the problem,
