- 1). Square the difference in the y-coordinates. For example, if your points are (21, 25) and (26, 37), the difference in the y-coordinates is 12, and 12 squared is 144.
- 2). Square the difference in the x-coordinates. For this example, since your points are (21, 25) and (26, 37), the difference in the x-coordinates is 5, and 5 squared is 25.
- 3). Calculate the sum of the squares. In this example, add 144 and 25 to get 169.
- 4). Calculate the square root of the sum of the squares to find the distance between the two points. In this example, the square root of 169 is 13.
