To find the distance between two points, we use Pythagorean Theorem. It can be obtained by creating a triangle and finding the length of the hypotenuse. The hypotenuse will be the distance between two points.

According to the Pythagorean Theorem, the sqaure of the hypotenuse is equal to the sum of the square of the other two sides of a right triangle. This formulae is applied to the two coordinates $(x_{1},  y_{1})$ and $(x_{2},  y_{2})$. Then the formula for calculating distance between two points is given by
$d  =  \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}$ where d is the distance between two points

       $x_{1}, y_{1}$ are the coordinates for one point

       $x_{2}, y_{2}$ are the coordinates for another point
           Distance Between Two Points
 
To find the distance between two points, follow these steps:
Step 1: Observe the points $(x_{1},  y_{1})$ and $(x_{2},  y_{2})$.

Step 2: Apply the distance formula    

           $d  =  \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}$

            Substitute the values and find the distance.
