Shapes of Constant Width - Reuleaux Triangles

A Reuleaux triangle is a geometric shape formed by connecting the vertices of an equilateral triangle with circular arcs, where each arc is centered at the opposite vertex, resulting in a curve with a constant width, meaning the distance between any two parallel tangents drawn to the shape is always the same, regardless of its orientation; essentially, it's the simplest non-circular shape with constant width, similar to how a circle has constant width across all its diameters.
