Impossible Triangle
Weird looking triangle illusion picture! Is it possible to have this triangle in real life?
The Penrose triangle, also called the tribar (Cerf), tri-bar (Ernst 1987), impossible tribar (Pappas 1989, p. 13), or impossible triangle, is an impossible figure published by Penrose and Penrose (1958).
