新gre数学考点介绍：Geometric Figures
<p> 新<span word="gre">gre</span>考试实施以来，不仅对写作部分茫然不知所措，就连我们所擅长的数学也甚是担忧，相信这其中的原因还是由于考生在新<span word="gre">gre</span>数学复习时没有把基础打牢。如果新版<span word="gre">gre</span>数学基本考点都没有复习到，如何能拿到分数呢?所以说，想要新版<span word="gre">gre</span>数学考好，复习的时候一定要把基本概念和重要考点都弄扎实。</p><p> <span word="Geometric">Geometric</span> <span word="Figures">Figures</span></p><p> <span word="If">If</span> <span word="a">a</span> <span word="point">point</span> <span word="is">is</span> <span word="selected">selected</span> <span word="at">at</span> <span word="random">random</span> <span word="inside">inside</span> <span word="a">a</span> <span word="geometric">geometric</span> <span word="figure">figure</span>, <span word="then">then</span> <span word="the">the</span> <span word="probability">probability</span> <span word="that">that</span> <span word="the">the</span> <span word="selected">selected</span> <span word="point">point</span> <span word="lies">lies</span> <span word="inside">inside</span> <span word="a">a</span> <span word="particular">particular</span> <span word="region">region</span> <span word="is">is</span> <span word="the">the</span> <span word="ratio">ratio</span> <span word="of">of</span> <span word="their">their</span> <span word="areas">areas</span>:</p><p> <span word="area">area</span> <span word="of">of</span> <span word="the">the</span> <span word="particular">particular</span> <span word="region">region</span> <span word="inside">inside</span> <span word="the">the</span> <span word="figure">figure</span>/<span word="area">area</span> <span word="of">of</span> <span word="the">the</span> <span word="whole">whole</span> <span word="figure">figure</span>.</p><p> <span word="Example">Example</span>:</p><p> <span word="The">The</span> <span word="probability">probability</span> <span word="that">that</span> <span word="a">a</span> <span word="randomly">randomly</span> <span word="selected">selected</span> <span word="point">point</span> <span word="within">within</span> <span word="the">the</span> <span word="square">square</span> <span word="lies">lies</span> <span word="inside">inside</span> <span word="the">the</span> <span word="circle">circle</span>=<span word="area">area</span> <span word="of">of</span> <span word="circle">circle</span>/<span word="area">area</span> <span word="of">of</span> <span word="square">square</span>=<span word="r">r</span>2/= /4.</p><p> <span word="Remember">Remember</span>:</p><p> <span word="If">If</span> <span word="the">the</span> <span word="particular">particular</span> <span word="region">region</span> <span word="is">is</span> <span word="not">not</span> <span word="completely">completely</span> <span word="inside">inside</span> <span word="the">the</span> <span word="figure">figure</span>, <span word="then">then</span> <span word="use">use</span> <span word="only">only</span> <span word="the">the</span> <span word="area">area</span> <span word="that">that</span> <span word="is">is</span> <span word="inside">inside</span> <span word="the">the</span> <span word="figure">figure</span>.</p><p> 由于美国数学基础教育的难度增加导致数学考试越来越难，但新<span word="gre">gre</span>数学复习考点都是高中时候学到的知识点，考生不要过于紧张，把基本概念弄明白，再记住一些新版<span word="gre">gre</span>数学必备的词汇，那么相信新版<span word="gre">gre</span>数学应该没有问题。</p><p> </p><p> </p>
