对称是广泛的存在于自然界中的一种关系,是自然界中绽放出最绚烂的花朵之一,它给人以美的浸润.对称的本质是两个物体或两个图形相对和相称.用数学思考问题的方式舍弃物体的其他属性,抽象成两个几何图形,它表现出两个图形大小、形状完全相同,只是位置有了变化.用解析几何的方法研究对称问题,是高中数学内容的重要应用,也是处理几何问题 Symmetry is a kind of relationship that exists in nature and is one of the most gorgeous flowers blooming in nature, which gives a beautiful infiltration. The essence of symmetry is that two objects or two figures are relative and commensurate. The Problem Way Discard the other properties of the object, abstracted into two geometries, which exhibit two shapes of the same size, the same shape, but a change in position. Using analytic geometry to study symmetry is an important application of high school math content , But also deal with geometric problems
