they can be but are not always. for example, in a square, each interior angle is 45 degrees. Adjacent simply means that one next to another and congruent means having the same measure. So in this example, adjacent angles are congruent.
However, in a scalene triangle, no two angles are the same and therefore cannot be congruent.
I hope this is what you are asking

square and a rectangle
Draw to lines intersecting each other. The angles across from each other will be both congruent and adjacent
yes but adjacent angles are not.
Congruent *apex
Sometimes they are, sometimes not.
Rhombus' Congruent AnglesIt's not the adjacent angles of a rhombus that are congruent, but the diagonal ones.
If all adjacent angles are congruent, it can only be a rectangle (or square).
Rectangles have congruent adjacent angles.
An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.

That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
Congruent *apex
Sometimes they are, sometimes not.
Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
