A parabolic shape is a curved line that forms a U-shape, like an arch. The term 'parabolic shape' is often used to describe the shape of an ARC, which is a three-dimensional curve formed by the intersection of a plane and a cone. The term 'ARC' is derived from the Greek word 'arkos, ' meaning 'BOW.' An ARC is also known as a parabola, which is a two-dimensional figure that has a symmetrical shape. The term 'parabolic shape' is used to describe the shape of many objects, including satellite dishes, roller coasters, and even some bridges.
