How to find distance between two points ?
To find distance between points $A(x_A, y_A)$ and $B(x_B, y_B)$, we use formula:
$$ {color{blue}{ d(A,B) = sqrt{(x_B - x_A)^2 + (y_B-y_A)^2} }} $$
Example:
Find distance between points $A(3, -4)$ and $B(-1, 3)$
Solution:
In this example we have: $x_A = 3,~~ y_A = -4,~~ x_B = -1,~~ y_B = 3$. So we have:
$$ begin{aligned} d(A,B) & = sqrt{(x_B - x_A)^2 + (y_B-y_A)^2} d(A,B) & = sqrt{(-1 - 3)^2 + (3 - (-4) )^2} d(A,B) & = sqrt{(-4)^2 + (3 + 4 )^2} d(A,B) & = sqrt{16 + 49} d(A,B) & = sqrt{65} d(A,B) & approx 8.062 end{aligned} $$

How to find midpoint of line segment ?
The formula for finding the midpoint $M$ of a segment, with endpoints $A(x_A, y_A)$ and $B(x_B, y_B)$, is:
$$ {color{blue}{ M~left(frac{x_A + x_B}{2}, frac{y_A + y_B}{2}right) }} $$
Example:
Find midpoint of a segment with endpoints $A(3, -4)$ and $B(-1, 3)$.
Solution:
As in previous example we have: $x_A = 3,~~ y_A = -4,~~ x_B = -1,~~ y_B = 3$~. So we have:
$$ begin{aligned} M~left(frac{x_A + x_B}{2}, frac{y_A + y_B}{2}right) M~left(frac{-1 + 3}{2}, frac{3 - 4}{2}right) M~left(frac{2}{2}, frac{-1}{2}right) M~left(1, frac{-1}{2}right) end{aligned} $$

Try our 2D distance formula calculator between two points in a 2-dimensional Cartesian plane. Use the marker to measure distances. How to calculate the distance between two points on a Cartesian system?In order to calculate the distance between two points on a plane, you must have the coordinates of each of the two points. In a two-dimensional landmark, you must know the abscissa and the ordinate. Some generalities:. The abscissas are generally denoted “x” and refer to the horizontal measurement of the plane. The ordinates are often denoted “y” and refer to the vertical measurement of the plane.Once these elements have been obtained, simply use the calculation formula: distance = √ ((x2-x1) ^ 2 + (y2-y1) ^ 2) Distance in 2 dimensions.
2D Distance Calculation with StepsYou have to now that the formula given above is made from the. If we consider the following data:. x1=5. x2=9.

y1=8. y2=3We have to complete the formula like this: distance = √ ((9-5) ^ 2 + (3-8) ^ 2) Thus, here are all steps with our example:. distance = √ ((8-5) ^ 2 + (3-8) ^ 2). distance = √ ((4) ^ 2 + (-5) ^ 2). distance = √ (16 + 25). distance = √ 41.
distance ≈ 6.328485.
