Question

two pairs of adjacent angle​

Answer 1

A Linear Pair is two adjacent angles whose non-common sides form opposite rays. ... If two angles form a linear pair, the angles are supplementary. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary.

Answer 2

Answer:

two angles are adjacent when they have common side and common vertex (corner point )

and don't overlap
