A. always true. Two angles are supplementary if the sum of their measures is 180°.
B. never true. Two angles are complementary if the sum of their measures is 90°.
C. sometimes true. Two angles are adjacent if they share a common vertex and side. They can only be complementary if the sum of their measures is 90°, which is not always the case for adjacent angles.
Determine if each of the following statements is always true, sometimes
true or never true.
A. The sum of the measures of two supplementary angles is 180°.
B. The sum of complimentary angles is 180°.
C. Two adjacent angles are complementary.
