ANY two angles that total 90o, eg the "other" angles in a right-angled triangle.
A polygon with six or more sides, in which four of the angles are right angles and the other angles are not. These others are of any type - as required. It cannot be a pentagon because, if 4 angles are right angles, the fifth would be 180 degrees!
No, these are two quite different things. "Supplementary" means that the sum of the angles is 180 degrees. The angles need not be consecutive; on the other hand, two consecutive angles can have any measure, not always 180 degrees.No, these are two quite different things.

A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
Adjacent angles are simply two angles that are next to one another and share one side. There is nothing else unique about these angles, and they are measured as one would measure any other angles.
The answer depends on your knowledge of any of the other angles in the intersections.
Angles in trigonometry are the same as any other angles. They are a measure of the separation between two lines which meet at a point.

Rectangles have only right angles (9o degrees angles) whereas other quadrilaterals can have any kind of angles, as long as they have 4 sides.

You would have to be given other information about the angles that would let you deduce that they are equal. For example any two right angles are equal. If two parallel lines are cut by a transversal, the alternate interior angles are equal.
A trapezium has 4 internal angles and 4 external ones, just like any other quadrilateral.
If you have the other two angles, you can subract them from 180 degrees, which is the sum of the angles in any triangle.
