ALL quadrilaterals have 4 angles
the two types of quadrilaterals that have four right angles are a square and a 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, 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.
Squares
A parallelogram, a rhombus, kites, arrowheads, trapezium and irregular quadrilaterals. However, some kites, arrowheads, trapezium and irregular quadrilaterals can have one (or more) right angles.
Nope, irregular quadrilaterals are like a box of chocolates - you never know what you're gonna get! They can have all sorts of angles, but having a right angle is not a requirement for being irregular. So, in the wise words of Forrest Gump, irregular quadrilaterals and right angles are like peas and carrots - they don't always go together.
quadrilaterals
ALL quadrilaterals have 4 angles
Always 360 degrees
A kite or some irregular quadrilaterals.
Not always because its possible to have a trapezoid with 2 right angles and an obtuse angle plus an acute angle and the 4 interior angles must add up to 360 degrees

The two quadrilaterals that have four right angles are rectangles and squares.
Rhombuses and trapezoids have no right angles by definition.
The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.
Some kites and irregular quadrilaterals. Certainly not a trapezium or parallelogram.
