    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°.
