# Distance and Midpoint in 3D Geometry - Calculator

## Formulas Used in the Calculator

A free online calculator to calculate the distance $D$ between two 3 dimensional points $A = (A_x,A_y,A_z)$ and $B = (B_x,B_y,B_z)$ given by the formula $D = \sqrt { (A_x - B_x)^2 + (A_y - B_y)^2 + (A_z- B_z)^2 }$ and the midpoint $M$ of the segment $AB$ with the formula given by $M = \left(\dfrac{A_x + B_x}{2} , \dfrac{A_y + B_y}{2} , \dfrac{A_z + B_z}{2} \right)$ is presented.

## Use of the Calculator

Enter the coordinates $x, y$ and $z$ of each point and press "calculate". The outputs are the distance $D$ and the coordinates $x, y$ and $z$ of the midpoint $M$.

 $A =$ (1 , 2 , 3 ) $B =$ (4 , 5 , 5 ) $D =$ $M =$ ( , , )
