Rectangles or squares; both of these have only right angles, so all the angles are congruent.

square and a rectangle
All quadrilaterals have diagonally adjacent angles.
quadrilaterals are consecutive and opposite angles always congruent?
Rectangles have all angles congruent,
The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.
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.
