The Reulot triangle is the area of intersection of three equal circles with centers at the vertices of a regular triangle and radii equal to its side. The non-smooth closed curve bounding this figure is also called the Reulot triangle. This is the simplest form of a constant width curve. Its two-dimensional equivalent is the Reulot tetrahedron.
