if a figure is a square, then it is a regular quadrilateral
No. The sum of the angles in any 4-sided shape must all ways add up to 360 degrees. So if 3 of the angles in such a shape are right angles the 4th must be as well, which would make the shape a rectangle.
No but it can have 2 right angles with 1 obtuse angle and 1 acute angle that add up to 360 degrees
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.
It doesn't have to, but it can. A trapezoid is any shape in which there is a pair of parallel sides. This means that a square can be classified as a trapezoid. But notice that a four-sided shape can never have ONLY three 90° angles. The sum of angles of a four-sided shape is 360--this means that if you have three 90° angles, then the remaining angle must be 360-3(90) which is 90°, giving you four right angles. * * * * * No you cannot. As indicated in the second paragraph of the above answer, three right angles implies that all four angles are right angles and that makes the figure a rectangle (or a square).
I dont know ;3

Yes, a trapezoid can have 3 right angles.
No.
No.No.No.No.
no, because three right angles don't even make 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.

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.
No but it can have 2 right angles with 1 obtuse angle and 1 acute angle that add up to 360 degrees
