The term "kidney-shaped" refers to an object or design that resembles the shape of a human kidney, which is typically oval with a slight indentation on one side. This shape is often used in various contexts, such as furniture, dishes, and even garden designs, where a smooth, curved form is desired. In geometry, kidney-shaped objects can be described as having a rounded, asymmetrical outline. This shape is not only aesthetically pleasing but also functional, as it can fit well in tight spaces or create a unique visual appeal in design elements like tables or planters.
