Penrose Triangle
Also known as the Impossible Triangle
It is an optical illusion of an illogical triangle.
Can be drawn on paper.
But cannot exist as a proper solid object.
First created by Swedish artist Oscar Reutersvärd in 1934, and independently devised and popularized in the 1950s by psychiatrist Lionel Penrose and his son, prominent Nobel Prize-winning mathematician Sir Roger Penrose.
Roger Penrose described it as "impossibility in its purest form".
It was featured prominently in the works of Dutch artist M C Escher (1898-1972), whose earlier depictions of impossible objects partly inspired the Penrose Triangle.
