Is it possible to create a trapezoid-shaped geometric figure like this one?

To get this image, I created this PNG image of a diagonal:

And then I placed it next to a rectangle of the same color.
Would it be possible to achieve the same effect using only two geometric elements?

Hi @Cesco. Rather than making all the shapes, create the shape in the middle (the white area) and place it on a page with a blue background. Then you have one shape which you can place anywhere on the page. You can’t currently produce these shapes in Sitely. One day maybe!!!
