问题 A regular n-side polygon and a regular (n+1)-side polygon have (2n+1) interior angles in total.
Quantity A: The median of (2n+1) interior angles
Quantity B: 90
选项 A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案 D
解析 正n边形的内角角度为(设为a)，正n+1边形的内角角度为(设为b)，a＜b。该组数据为n个a和n+1个b组成，奇数个数据的中位数为最中间的数，为b=。n=3时，Quantity A=Quantity B；n＞3时，Quantity A＞Quantity B。故答案为D。
