Poster from the category art with an illustration of a Penrose triangle. A Penrose triangle is a geometric figure created by the British mathematician and philosopher Sir Roger Penrose. It has no interior angle equal to 360 degrees, which is an impossibility in Euclidean geometry. It is an optical illusion that is perceived as a triangle that has a convex curve joining the three corners.
