下面是为大家搜集整理的10道典型的新GRE数学几何练习题,希望大家不要认为国内考生在新GRE数学方面有优势就轻视GRE数学考试,而是要认真练习,努力备考,争取取得满分。
1.两条直线比斜率:
一条x轴intercede 3,y轴intercede 4, 和一条x轴intercede 4,一个y轴intercede 3.
解:slope1=/=-4/3 slop2=/=-3/4
注意由于两条直线的斜率是负数, 后者斜率大一些.
2.直线y+x=4, 与x^2+y=4交点的距离?
解:meykey:根号2。 4-x=4-x2
3.有一个题目觉得很有意思,就是问y=xx+1和y=x-1的图是下列哪一个?
比较简单。选的是D。
4.一直线在X轴截距为a,Y轴上截距为b,问斜率是多少。
解:两点式:列出两点,k=/=-b/a
5.圆里头最长的线段是哪条?
就是直径
6.图中一三角形,X,,Z分别为两个角的外角,Y为第三个内角,问X+Z与180+Y的大小?
解: Y++=180
可退出Y+180= X+Z 所以相等
7.钝角三角形,两短边为6,8,问其面积与24的大小。
解:
8.三角形三边为8,5,6,问5,6 夹角于90谁大?
mykey:前者大.
9.三角形三条边6,8,10.5,问6和8所对的两个角相加与90度比
解:小于。
10.45度的直角三角形,面积是16,问斜边。
解: 答案是8
以上内容即是10道新GRE数学几何练习题,希望考生能多加练习,通过多做题来准确把握出题者的出题思路,了解题目难易程度,更加了解考试的题型,做到熟能生巧。愿大家都能取得好的成绩!
