Calculates the Distance Between Two Points.  
 

This section describes the distance formula and how we can calculate the distance between to end points.
The distance between two points can be calculated by using this formula only if you know the coordinates of both points. If two points are (x1, y1) and (x2, y2), the distance between these points can be calculated by using the following formula:
This formula is being used in geometry in Mathematics. Due to its importance in the subject, students must be aware of this formula and should be able to use it to calculate the distance. The same formula is used to calculate the radius of a circle. By using this formula radius can be calculated if the mid point and a point on the circumference is known.
During the calculation of distance, often people mix the coordinates of points. Make sure, that during calculation, right values are being used for the right coordinates.
