平移、旋转是现实生活中广泛存在的现象,是现实世界运动变化的最简洁形式之一.它们不仅是探索图形性质的重要手段和方法,而且也是解决现实世界中具体问题以及进行数学交流的重要工具. 近年来,平移、旋转成为初中数学教学的重点之一,同时也成为许多中考新颖试题的载体.因此,正确理解和掌握平移、旋转的课程内容,成为初中数学学习的必要环节之一.
Translation and rotation are phenomena that exist widely in real life and are one of the simplest forms of changes in the real world movement. They are not only important means and methods for exploring the nature of graphics, but also are important for solving specific problems in the real world and for conducting mathematical exchanges. Tools. In recent years, translation and rotation have become one of the focuses of mathematics teaching in junior middle schools. At the same time, they have also become the carrier of many new examination questions. Therefore, correctly understanding and mastering the content of translation and rotation has become one of the necessary links for junior middle school mathematics learning.
