Question

Which statement below is ALWAYS TRUE?

(A) Complementary angles are both acute angles.

(B) Any two acute angles are complementary angles.

(C) Supplementary and Complementary angles are always adjacent angles.

(D) Supplementary angles are both obtuse angles

Answer 1

The statement that is always true is that supplementary and complementary angles are always adjacent angles.

Step-by-step explanation:

The statement that is ALWAYS TRUE is (C) Supplementary and Complementary angles are always adjacent angles. Supplementary angles are two angles that add up to 180 degrees, while complementary angles are two angles that add up to 90 degrees. Adjacent angles are two angles that have a common vertex and a common side between them. So, it is always true that supplementary and complementary angles are adjacent angles because they share a common side.
