# Distance Between Three Points Calculator

Here is a simple online calculator to calculate the distance between three points. The distance between two or more points could be determined by accumulating the distances between each point and their corresponding end points. In the below distance between three points calculator, enter the values for three points (x1, y1), (x2,y2), (x3,y3) and click on calculate. Finding distance between 3 points in a triangle also helps you find the centroid of that triangle.

## Find the Distance between 3 Points

Here is a simple online calculator to calculate the distance between three points. The distance between two or more points could be determined by accumulating the distances between each point and their corresponding end points. In the below distance between three points calculator, enter the values for three points (x1, y1), (x2,y2), (x3,y3) and click on calculate. Finding distance between 3 points in a triangle also helps you find the centroid of that triangle.

#### Formula:

d1 = √((x2 - x1)2 + (y2 - y1)2) d2 = √((x3 - x2)2 + (y3 - y2)2) d3 = √((x1 - x3)2 + (y1 - y3)2) d = (d1 + d2 + d3) / 3 Where, (x1, y1), (x2, y2), (x3, y3) = Points d1, d2, d3 = Distance between 2 points d = Average Distance

### Example:

Find the distance between 3 points (1,2) (3,4) (5,6)

#### Solution:

x1, y1 = 1, 2
x2, y2 = 3, 4
x3, y3 = 5, 6
d1 = √((3 - 1)2 + (4 - 2)2)
= √(4 + 4)
= 2.83
d2 = √((5 - 3)2 + (6 - 4)2)
= √(4 + 4)
= 2.83
d3 = √((1 - 5)2 + (2- 6)2)
= √(16 + 16)
= 5.65
d = (2.83 + 2.83 + 5.65) / 3
= 3.77
