Distance a2 b2 Imagine you know the location of two points A and B like here. Find distance between points A3 -4 and B-1 3 Solution. Below is a diagram of the distance formula applied to a picture of a line segment.
Colorblue dAB sqrtx_B - x_A2 y_B-y_A2 Example.
The distance is the same in either direction going from point 1 to point 2 or vice versa. Provide the x1 y1 x2 and y2 values to find the distance using this distance between two points calculator. Thats what were trying to figure out. The distance between 32 and 78 is sqrt 52 or approximately 721 units.
