A "Quarter Turn" refers to a rotation of 90 degrees in a specific direction. This term is commonly used in various fields, including engineering, dance, and sports. In engineering, it can describe the movement of a valve or lever, while in dance, it may indicate a specific step or position change. In sports, a quarter turn can be crucial for athletes, especially in gymnastics or figure skating, where precise angles affect performance. Understanding this concept helps in executing movements accurately, ensuring better control and coordination during activities that require turning or pivoting.
