A trapezoid has top and bottom edges of different lengths. It can suggest a grounded base or a perspective panel while adding direction.
`topWidth` and `bottomWidth` set the half-widths of the top and bottom edges, each from 0.01 to 1. `height` is the half-height from 0.01 to 1, and `rotation` turns the shape from 0 to 360 degrees.
The top can also be wider than the bottom, so set the two widths deliberately when the direction matters. Place it beside `Parallelogram` to show the difference between slanted sides and unequal edge widths, and check the narrower side's spacing when placing text over it.
When to use
Use it for bases, banners, or perspective-like panels that need different top and bottom widths. It can also emphasize direction in a mark or diagram. Avoid it when you need parallel opposite sides or rounded corners.
