We should distinguish the difference between a central angle and an inscribed angle. #GREMaths #GMATMaths

在英语的几何中，无疑圆的术语会更为陌生些，例如circumference， 你需要区别它于四边形中的perimeter；radius，diameter，chord，secant，arc。以下给出类这些词汇的英文定义。 #GMATMaths #GREMaths

当面对数不清的数学运算公式时，最有效的记忆方式是理解公式中每一个缩写字母的含义例如A = area; S = side; P = perimeter; b = base; h = height，这些简单的缩写不会随着时间的推移而遗忘掉。 #GMATMaths #GREMaths

但凡能够读懂这道题目的学生都不会选择错误。但如何学会估算是更有效的提高做题速度。我们知道这道题目需要用22%＊total number 729，如果我们能够直接估算出20%的数值基本为150左右，那么选项中最接近这个数值的答案一定是正确的。 #GREMaths...

面对这道不定式最快的解决方式依然是我们之前讲解过的代入法。x=2，A 有可能，x=- －1/2，B 有可能。x = －2，C不可能。所以最终的答案为B。 #GREMaths #GMATMaths

解决这类的数学题最好的方法就是选择代入法当r=1时，Quantity B is greater，当r=10时，Quantity A is greater，所以选项 D是正确答案。 #GREMaths #GMATMaths
