A regular-shaped object is one that has symmetry. Squares, rectangles, circles and cubes are examples of regular objects, because each object has sides or angles that share certain properties.
Regular-shaped objects are two or three-dimensional and have common characteristics, such as symmetry in length, width, angle size, or for rounded shapes, symmetry in radii or circumference. Regular two-dimensional shapes include rectangles, squares, triangles and circles, while regular three-dimensional shapes include rectangular boxes, cubes, spheres and cones. Other shapes with more sides and angles are also regular if some of those sides or angles are the same. If no two sides or angles on the object are the same, an object would be considered irregular.
