    单选题
    An isosceles triangle has one angle with a measure greater than 95° and another with a measure of x°. Which of the following must be true?
    A

    x > 85

    B

    x = 85

    C

    x =42.5

    D

    x <42.5

    E

    x > 42.5


    正确答案: B
    解析:
    等腰三角形有两个角相等,且三角形内角度数总和为180度,所以不可能有两个角大于95度,故其他两个角为x度。假设其中一个角为96度。则x + x + 96 = 180 , 2x = 84, x = 42,根据以上选项,可知D为正确选项。

    Which one of the following is a counterexample to the statement “If two angles are supplementary, then they are right angles?”
    A

    If two angles are complementary, then they are not right angles.

    B

    If two angles are fight angles, then they are supplementary.

    C

    If two angles are not supplementary, then they are not right angles.

    D

    If two angles are supplementary, then one could measure 100° and one could measure 80°.

    E

    If two angles are not fight angles, then they are not supplementary.


    正确答案: E
    解析:
    A counterexample is an example that proves a statement to be false. Answer D shows one example where angles are supplementary but are not right angles, since one measures 100° and the other measures 80°.
