平面几何是一棵古老的大树,其枝根脉络清晰,推理逻辑严谨,证明思维灵活,不知迷倒多少代人.平面解析几何题目大都有深刻的平面几何背景,一道好的题目,既考查思维能力,又给人赏心悦目的感觉.2007年北京的模拟题中,很多是把平面几何中图形的基本性质与圆锥曲线加以综合,使题目既有综合性,又有灵活性,相映成趣,令人耳目一新,如同生机盎然的大树所盛开的鲜花,绚丽多彩.下举几例与读者共享.
Plane geometry is an old tree, its branch veins are clear, reasoning logic is rigorous, it proves that the thinking is flexible, and it doesn’t know how many generations are lost. The plane analytical geometrical problems all have deep plane geometrical backgrounds, a good topic, and they are examined. Thinking ability, but also gives people a pleasing feeling. In 2007 in Beijing simulation questions, many of the basic characteristics of the graphics in the plane geometry and conic curves are integrated, so that the title is both comprehensive and flexible, side by side, make The people are refreshing and fresh, like the flowers blooming in the vitality of the trees, colorful and colorful. Here are some examples of sharing with readers.
