It depends on what aspect you wish to measure: the lengths of its edges, the area of its faces, its volume, its angles, etc. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
It is a trapezoid which is a 2D shape whereas the rest are 3D shapes.

To determine the measure of angle ( DAB ) in an isosceles trapezoid, you need to know the measures of the other angles or the lengths of the bases. In an isosceles trapezoid, the base angles are equal, so if you have the measure of one base angle, angle ( DAB ) will be the same. If additional information about the trapezoid is provided, please share it to get a more precise answer.
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.
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.
There is no figure to be seen but an isosceles trapezoid will have equal base angles.
Simply measure it and the parallel bases of a trapezoid will have different lengths.
