no, because three right angles don't even make a square...
Yes, a trapezoid can have 3 right angles.
It would be impossible. A trapezoid can't have three right angles. It would just make a rectangle.
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.
I dont know ;3
A trapezium can have at most two right angles. But it need not have any.It is a quadrilateral and so the sum of its four angles must be 360 degrees. If there are 3 right angles then they sum to 3*90 = 270 degrees and so the fourth must be 360-270 = 90 degrees. Therefore it has four right angles and then is no longer a trapezium but a rectangle!
a trapezoid has no right angles whatsoever. no they cant because trapezoids have only 4 sides and dented
No because the 4th angle would have to be 90 degrees.
if a figure is a square, then it is a regular quadrilateral
No but it can have 2 right angles with 1 obtuse angle and 1 acute angle that add up to 360 degrees
parallelogram
No. A trapezoid is any four sided shape which has at least two parallel sides. If it is four sided, cannot have exactly four right angles.
