The Penrose triangle, also known as the Penrose tribar, is an impossible object .
The tribar can only exist as a 2-dimensional drawing, since it exploits the overlapping of parallel lines drawn in different perspectives.

 

The Penrose triangle appears to be solid on the page, but it cannot be built.
