It meets all definitions I can find, and it would seem that a straight angle can be adjacent.
Definition: (1) Two angles that share a common side and a common vertex, but do not overlap. (2) An adjacent angle is either of two angles having a common side and a common vertex.
Adjacent angles are angles that have a common ray coming out of the vertex going between two other rays. Another way of saying this is that adjacent angles are next to one another, side by side or adjacent. (Hence the name)
It is an angle next to another one in a polygon.

The sum of an adjacent interior and its exterior angle will total to 360°. If the angles were to be equal, they would both have to be 180°. An angle of 180° is a straight line. A polygon may be composed of straight lines that intersect at vertices but a straight line has no vertex. That being the case, the answer to your question is "No".
an adjacent corresponding angle is an angle which is adjacent to a particular angle as well as corresponding.
Each angle is 180/5 = 36 degrees
No? Wouldn't they then be supplementary? Opposite rays make a straight angle/line, and if the exterior sides made the straight angle, the adjacent angles would be supplementary. ...Right?
A straight angle is defined as 180 degrees.If you didn't know that, you could take two of them and place them adjacent, or "back to back", and see that they add up to a full 360 degrees.
