The term 'twisted shape' can be described as a HELIX, which is a five-letter word. A HELIX is a three-dimensional shape that is formed by a continuous curve that winds around a central axis. It is often seen in nature, such as in the structure of DNA molecules and in the shape of a snail shell. Helices are also used in engineering and architecture, such as in the design of spiral staircases and in the construction of suspension bridges.
