平移与旋转这部分知识不仅在实际生活中应用广泛,还有利于培养同学们的实践与操作能力,形成空间观念和运动变化意识,所以在中考中占有十分重要的地位.其常见的题型有填空、选择、作图、综合题等.常结合轴对称、三角形相似(全等)、勾股定理、方程、函数等知识进行综合应用.解这类题要求同学们具备扎实的数学基本功,较强的观察力,丰富的想象力及综合分析问题的能力,解题时要切实把握几何图形的运动过程,并注意运动过程中的特殊位置.明确图形旋转前后哪些是不变的、量,哪些是变化的量.本文将精选几例有关图形的平移和旋转的中考题加以分析,旨在引导同学们学会分析和解答此类问题的能力. This part of the knowledge of translation and rotation is not only widely used in real life, it is also conducive to the training of students’ practical and operational skills, the formation of spatial concepts and awareness of movement change, so it occupies a very important position in the examination. Its common questions are Fill in blanks, choices, drawings, synthesis questions, etc. Often combined with axisymmetric, triangular similar (congruent), Pythagorean theorem, equations, functions and other knowledge for comprehensive application. Solve this type of problem requires that students have a solid mathematical basic skills, Strong observation power, rich imagination and ability to comprehensively analyze problems. When solving a problem, we must really grasp the movement process of the geometric figure and pay attention to the special position in the movement process. What are the invariable, quantitative, which before and after the rotation of the figure? It is the amount of change. This article will select a few examples of the analysis of the translation and rotation of the graphics to analyze, in order to guide the students to learn to analyze and answer such questions.
