Answer:
Statement A is correct
Statement B is incorrect
Step-by-step explanation:
a)Sum it up: Supplementary angles are two angles whose sum is 180°. A linear pair (two angles that form a line) will always be supplementary. The two angles can be adjacent or non-adjacent.
b)No it is not necessary.
Two angles are said to be adjacent when they have common vertex, a common side but do not overlap. They can be of any measure. For example, 33° and 25° can be two adjacent angles.
