It is a trapezoid which is a 2D shape whereas the rest are 3D shapes.
A trapezoid prism
A regular trapezoid (!) is a square. And each interior angle of a square is 90 degrees.
You find the surface area of each of its six faces and add them together.
Only when it is an isosceles trapezoid otherwise no.
Trapezoid is 3D. The shadow of this shape is called Trapezium.

Oh, dude, you mean a 3D trapezium? That's like calling a square a 3D square, it's just a trapezoid. Adding that extra dimension doesn't change its name. It's still just a trapezoid, but with a little more pizzazz.
Simply measure it and the parallel bases of a trapezoid will have different lengths.
There is no figure to be seen but an isosceles trapezoid will have equal base angles.
