a linear pair!
A pair of adjacent angles whose non-common sides are opposite rays are called a linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

yes
Not clear what exactly the question is.
Opposite angles.
Yes, in 3-dimensional space.
Any pair of adjacent angles.
They are simply angles next to each other
two angles that are adjacent and supplementary are said to form a linear pair of angles.
Two angles are adjacent if they have the same vertex, share a side and do not overlap. It is, therefore, perfectly possible for two obtuse angles to be adjacent. In fact, every pair of adjacent angles in a hexagonal tessellation (a honeycomb, for example), consists of a pair of obtuse angles (120 degrees).
