Perpendicular lines.
Not necessarily. A linear pair of angles must be supplementary but supplementary angles need not form a linear pair. For example, the opposite angles of a cyclic quadrilateral are supplementary but they are (by definition) not next to one another.
Yes if it is in the form of an isosceles triangle with the other 2 acute angles being equal

Perpendicular lines.
yes they are because they meet to form at a right angle

They would be called "supplementary angles" because 90º + 90º = 180º and any two angles that add to 180º form straight, parallel, or congruent lines.(Angles that add to 90 º are called complementary.)
Supplementary angles.
If they do , the angles are supplementary !
Supplementary angles.
Supplementary angles.
Supplementary adjacent angles add up to 180 degrees
They are congruent angles.
they form a straight line
