It would be impossible. A trapezoid can't have three right angles. It would just make a rectangle.
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).
You can have two right angles and still be only a trapezoid. With three right angles then it would be a rectangle.
Both a triangle and a trapezoid are polygons with straight sides. However, a triangle has three sides and three angles, while a trapezoid has four sides and four angles. Additionally, both shapes have interior angles that add up to 180 degrees.
Not possible - that would mean the final angle would also have to be ninety degrees - making it a square or rectangle.
no
A trapezoid cannot have three right angles. If it did it would either need more than four sides, or it would be a rectangle or 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.

no, because three right angles don't even make a square...
No, because then it would be a rectangle.
The sum of all four angles is 360 degrees. If three of the angles were right angles then the fourth would have to be a right angle. You would then have a rectangle or a square, but not a trapezium.
That's three different shapes: a rectangle, a rhombus and a trapezoid respectively.

Nope. A trapezoid has 4 sides, but only 2 of the sides are parallel. If there were 3 right angles, the 4th angle would also have to be a right angle, and both opposing sides would be parallel.
