Answer 1

Here are the determinations for each statement:

A. The sum of the measures of two supplementary angles is 180°.

• Always true

B. The sum of complementary angles is 180°.

• Never true (The correct statement is that the sum of complementary angles is 90°.)

C. Two adjacent angles are complementary.

• Sometimes true (Adjacent angles can be complementary if their measures add up to 90°, but they are not always complementary.)

So putting it all together:

• A: Always true
• B: Never true
• C: Sometimes true
