What quadrilaterals have congruent adjacent angles?
Rectangles or squares; both of these have only right angles, so all the angles are congruent.
What quadrilaterals have all four angles congruent?
squares, rectangles, some rhombuses .... I'm not sure all angles can be congruent
What shape has all four angles are congruent?
rectangles and squares have
Are all rectangles perpendicular?
Yes. The basic definition for a rectangle is 4 sides, four right angles(perpendicular), and opposite sides are congruent.
Are angles and sides of a parallelogram congruent?
In all parallelograms, opposite angles and opposite sides are congruent. If all four sides are congruent, it's a rhombus. If all four angles are congruent, it's a rectangle. If all four sides and all four angles are congruent, it's a square.
What quadrilaterals has all angles are congruent?
Rectangles have all angles congruent,
Can a rectangle be a square explain?
a rectangle has 4 right angles. A rhombus has four congruent sides. A square has four right angles and four congruent sides. All squares are rectangles because all rectangles have 4 right angles, and all squares have four right angles. But not all rectangles are squares because not all rectangles have congruent sides.
What quadrilateral has 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.
What quadrilaterals have congruent adjacent angles?

In which type of quadrilateral are consecutive angles congruent?
Rectangles;all angles equal 90 degrees
Why is a square also a rectangle?
Because there opposite sides are congruent. And all squares are rectangles, but not all rectangles are squares!
Which quadrilateral are consecutive angles always congruent?
All rectangles, including squares.
