Square and rectangle
The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.
no,all quadrilaterals have 4 right angles
No.
No, only squares and rectangles have 4 right angles.
No, one example is a kite that DOES NOT have two right angles. It is not a cyclic quadrilateral. A kite that does have two right angles is one.
No, a quadrilateral does not necessarily have any right angles. If it has a right angle, it will necessarily have four right angles, and will be a rectangle. But not all quadrilaterals are rectangles. As long as a polygon has four sides, it is a quadrilateral. It might have, for example, two angles of 100o and two angles of 80o.
No. A quadrilateral is any four-sided figure. The sides do not have to be of equal length, and the angles do not have to be right angles. So, all squares are quadrilaterals because they have four sides), but not all quadrilaterals are squares.
false
Rectangles or squares; both of these have only right angles, so all the angles are congruent.
All quadrilaterals have consecutive and opposite angles.
All quadrilaterals have diagonally adjacent angles.
No because a quadrilateral has 4 sides but doesn't have to have right angles. For example the. Trapezoid doesn't,t have right angles but it is a quadrilateral
