Definition: The term "sidesaddles" in the context of mathematics refers to a specific type of polygon with four sides and three vertices, also known as a quadrilateral. This shape is often used for counting triangles or other figures that have straight edges but no curved sides. Sidesaddles are named after their shape, which resembles a crescent moon, although they do not have any moons in the traditional sense. They are commonly found on some ancient Egyptian and Mesopotamian inscriptions,
