Optical illusion: Are the figures straight or inclined? [video]

Pay attention to the video above and see how the optical illusion deceives our brains and makes us believe that some objects in the image are tilted. However, all elements of the figure have the same distance and are positioned parallel to each other.

So why do we get the impression that objects are tilted? In fact, it is the diagonal lines drawn in opposite directions that give us the impression that the upper rectangle is tilted to the right. In addition, the small triangle positioned over the rectangle gives us the impression of weight, helping to make the optical illusion work.
