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 180⁰
B. The sum of complimentary angles is 180⁰
C. Two adjacent angles are complementary
A. Always true - Two angles are supplementary if their measures add up to 180⁰. Therefore, the sum of the measures of two supplementary angles is always 180⁰.
B. Sometimes true - Two angles are complementary if their measures add up to 90⁰. Therefore, the sum of complementary angles is 90⁰, not 180⁰.
C. Never true - Two adjacent angles share a common side and vertex. Adjacent angles are not always complementary; they can be any degree measure depending on the specific angles.
