The distance formula is a mathematical equation used to calculate the distance between two points. It can be used to measure distances on a two-dimensional plane or in three-dimensional space. The formula is simple yet powerful and is applicable to a variety of problems. It is also used in physics, engineering, and other sciences. By using the distance formula, one can quickly calculate the length of a line segment, the distance between two points, or the distance between multiple points. Knowing the distance between points can help us understand our environment better and make better decisions.
