Distance formula Algebraic expression that gives the distances between pairs of points in terms of their coordinates see coordinate system. It measures the distance between two points in space. For example you might want to find the distance between two points on a line 1d two points in a plane 2d or two points in space 3d.
The distance formula is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse.
Distance Formula The distance formula is a formula that is used to find the distance between two points. The line extending from the center of a sphere to any point on the outside edge of the sphere. Distance x 2 x 1 2 y 2 y 1 2. X1 - x22 y1 - y2212.
