Penrose triangle

The Penrose Triangle, also known as the "impossible triangle," is a visual paradox that depicts a three-dimensional object that cannot exist in the real world. Created by British mathematician Roger Penrose in the 1950s, it appears to be a solid triangle with three straight edges, yet its construction defies the laws of geometry. Each edge seems to connect in a continuous loop, creating an optical illusion that tricks the viewer's mind. The Penrose Triangle showcases how our perception can be deceived and is often used in art and design to illustrate concepts of impossibility and abstract thinking.
