问题 △RST is isosceles and ∠RST= 40°

Column A Column B
The sum of the measures of the two angles of 120°
△RST that have equal measure

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 △RST是等腰三角形，且∠RST=40o
解：本题的正确答案为(D)。比较的左项为△RST中两个底角的和，该题需分两种情况进行讨论：①∠RST是顶角，则两个底角的和为：180o-40o=140o ②∠RST是底角，则两个底角的和为：2×40o=80o
