if a figure is a square, then it is a regular quadrilateral
It would be impossible. A trapezoid can't have three right angles. It would just make a rectangle.
you cant because it would be a square
No you cant
Not possible - that would mean the final angle would also have to be ninety degrees - making it a square or rectangle.
It could be a 4 sided trapezoid having 2 right angles on one side wth an acute and obtuse angle on the other side. The 4 interior angles must add up to 360 degrees.
no
it is not possible
It would be impossible. A trapezoid can't have three right angles. It would just make a rectangle.
No, because then it would be a rectangle.
No because then it would then be a square or 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.
you cant because it would be a square
Well, honey, to draw a trapezoid with no right angles, you start by drawing two parallel lines of different lengths. Then you connect the ends of those lines with two slanted lines, making sure they're not perpendicular. Voila, you've got yourself a trapezoid with all angles different from 90 degrees. Now go show off your fancy geometric skills!
No you cant
No.
Draw two parallel lines of unequal length, and connect their end points. If you have a right angle, it is a right trapezoid. If the non-parallel sides are equal in length, it is an isosceles trapezoid.
