Some call them “shield bugs” because of their distinct trapezoidal shape.

由于它们独特的梯形形状， 有人称它们为“盾虫” 。

Then connect the floor and ceiling with trapezoidal walls and voila, you have an Ames Room.

然后用梯形墙连接地板和天花板，瞧，你就有了一个艾姆斯房间。

But not in the case of a trapezoidal window that our brains assume to be rectangular, hence the illusion.

但不是在我们的大脑假设是矩形的梯形窗口的情况下，这就是幻觉。
