It would be impossible. A trapezoid can't have three right angles. It would just make a rectangle.
a tetrahedron has 3 Right angles
No, if a trapezium had three right angles, it would mean the fourth angle would have to be 90 degrees. That would make it a square or a rectangle.
A pentagon with 3 right angles is considered to be an irregular pentagon because not all angles and all sides are equal.
In a three-quarter turn, there are three right angles. A right angle measures 90 degrees, so in a full turn (360 degrees), there are four right angles. Therefore, in a three-quarter turn (270 degrees), there are three right angles, as each right angle is 90 degrees.

no, because three right angles don't even make a square...
You can make a four sided shape with 3 right angles, but it must have another right angle, too. So technically, yes.
a right angle is 90 degrees. 3 right angles is 270 degrees. if you make you body turn 270 degrees then you pretty much just turned left or right but just the long way.

Yes, a trapezoid can have 3 right angles.

you cannot make a regular shape which has 3 right angles only, you will always end up with 4 right angles
no. if you have 3 right angles it is impossible to not have a 4th right angle which would then be a square
