The sum of the lengths of two sides of isosceles triangle K is 7. K has a side of length 4.
Column A Column B
The perimeter of K 11
选项
A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given
答案
D
解析
等腰三角形(isosceles triangle)K的两条边的和为7,K有一条边的长为4。
解:本题的正确答案为(D)。该题可分两种情况:(1)7是两腰的和,则4是底边长,K的周长等于11; (2)若7是腰与底边和,则腰长可能为3,也可能为4。当腰长为3时,对应K周长等于10;当腰长为4时,对应K的周长等于11。
