Quadrilateral means "four sides", and squares and rectangles do have right angles. Rhombuses are quadrilaterals, but do not 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
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.
An irregular quadrilateral doesn't need to have any right angles. It's possible for it to have one or two right angles, but no more than two of them.
A quadrilateral with 4 right angles is a rectangle
a quadrilateral with no right angle is?
-- Every quadrilateral has four sides.-- If it has no right angles, then it could be a parallelogram, a rhombus,a kite, a trapezoid, or any non-regular quadrilateral.
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
4 because the 4 interior angles of any quadrilateral add up to 360 degrees
It is a convex quadrilateral, as the remaining angles could be any two angles with a sum of 180 degrees.
If it is a quadrilateral it cannot be "not a quadrilateral"!
yes a quadrilateral does have 4 right angles
It is a rhombus that has 4 equal sides but no right angles.
Any quadrilateral in which at least one (and therefore at least two) angles are not right angles is not a rectangle. The majority of these do not have a specific name.
A quadrilateral having four right angles is called a rectangle.
The most right angles a triangle can possibly have is 1. Any more than that, and it has to be a quadrilateral.
a rectangle is any quadrilateral with four right angles
A quadrilateral can have four right angles.
A quadrilateral with no right angles can refer to most kites, most trapezoids, some parallelograms, and a few quadrilaterals that cannot be classified any more specifically.
A quadrilateral with four right angles is a rectangle. If all its sides are the same then it is a square.
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 with no right-angles would be a rhombus (or parallelogram) A rhombus has four sides, with opposite corner angles equal.
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.
Because a rectangle is any quadrilateral with four right angles.
It's impossible for a quadrilateral to have no equal sides and have right angles.
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
