a quadrilateral with no right angle is?
All quadrilateral have four angles. It is possible that all four angles are right angles, even if the quadrilateral is not a square (this would be a rectangle).
No a quadrilateral can't have 3 obtuse angles and 1 right angle because if a polygon did have 3 obtuse angles and 1 right angle then it would not even be a quadrilateral.
A quadrilateral with 4 equal sides and 4 right angles is a square.
A trapezoid can't have three right angles. A quadrilateral with three right angles must have a total of four right angles, since a quadrilateral's interior angles add up to 360. 360 - (3*90) = 90, so the fourth angle would have to be right as well. A quadrilateral with four right angles is not a trapezoid; instead it is a rectangle or a square.
if a quadrilateral has three right angles will also have have a fourth right angle. Making it a rectangle. The addition of all the angles in a triangle is 360 degrees. If there are three right angles, and you subtract their addition by 360, you will get ninty degrees.
A quadrilateral with 4 right angles is a rectangle
If it is a quadrilateral it cannot be "not a quadrilateral"!
A quadrilateral having four right angles is called a rectangle.
yes 4 right angles
A quadrilateral is any shape with four sides; angles can be acute or obtuse. A perfect square is the only quadrilateral with only right angles.
All quadrilateral have four angles. It is possible that all four angles are right angles, even if the quadrilateral is not a square (this would be a rectangle).
A quadrilateral can have four right angles.
It's impossible for a quadrilateral to have no equal sides and have right angles.
No, if it has right angles it is a special case, such as rectangle, but in general it does not have to have any right angles
No.
no
Right angles.
