The term 'flattened circle' is a description of an OVAL, which is a four-letter word. An OVAL is a shape that is similar to a circle but has been flattened on one side. It is a two-dimensional figure with two sets of parallel lines, one set longer than the other. The sides of an OVAL are curved, and the ends are pointed. Ovals can be found in nature, such as in the shape of eggs, and they are also used in art and design.
