a quadrilateral can have from 0 to 4 right angles.
But it can't have exactly three right angles. The interior angles of a quadrilateral sum to 360 degrees. If it had three right angles and x were the measure of the fourth angle:
3*90+x=360
x=360-270=90
So if it has three right angles, the fourth angle would be a right angle as well.
A quadrilateral with 4 right angles is a rectangle
yes 4 right angles
NO quadrilateral has, except rectangles and squares.
square
a trapeziod
A quadrilateral with 4 right angles is a rectangle
a quadrilateral with no right angle is?
If it is a quadrilateral it cannot be "not a quadrilateral"!
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.
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.
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
no
no
