A square and a rectangle
A rectangle and a square are two types of quadrilaterals having four equal angles, where each of them equals a right angle.
squares, rectangles, some rhombuses .... I'm not sure all angles can be congruent
Rectangles - and squares, as a special case.
no triangle do not have four congruent angles
A square and a rectangle
They are squares and rectangles that each have four congruent angles of 90 degrees which makes up a total of 360 degrees.
The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.
