Quadrilaterals are a generic class of polygons (shapes that have only straight sides) that simply have 4 sides. "Quadrilateral" literally means "4-sided". Given that, I'm sure you can think of 2 very common quadrilaterals that have right angles: the "rectangle", and a special form of rectangle called a "square". The name "rectangle" literally means "right angle", and is called such because all 4 sides of this type of quadrilateral are connected by right angles. A square is a rectangle, all four of whose sides are equal in length. So a square is a rectangle is a quadrilateral.
What else can I help you with?
What quadrilaterals have or could have diagonals that intersect at right angles?
Squares
What two types of quadrilaterals have four right angles?
the two types of quadrilaterals that have four right angles are a square and a rectangle
What 2 quadrilaterals have four right angles?
The two quadrilaterals that have four right angles are rectangles and squares.
What is the most right angles a quadrilateral can have?
Quadrilaterals have four sides, and therefore four angles, so the most right angles it could have is four, like a square.
Do irregular quadrilaterals have no right angles?
no
What to quadrilaterals have no right angles how do you know?
Rhombuses and trapezoids have no right angles by definition.
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.
Are all quadrilaterals cyclic quadrilaterals?
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.
What quadrilaterals have 0 right angles?
A quadrilateral with 0 right angles is a trapezoid, i know it looks like it has right angles IT DOES NOT!
Do quadrilaterals have right angles?
"Quadrilateral" simply means "four sided". Some quadrilaterals do have right angles; squares or rectangles, for example. Some have one or two right angles, but some don't have any right (90 degree) angles.
All quadrilaterals have 4 right angles?
No, only squares and rectangles have 4 right angles.
Is there a quadrilaterals that has no right angles?
Yes. A quadrilateral is any four sided figure, so you could draw any number of these figures that have no right angles...a parallelogram for instance.
