  • Distance Formula

    To calculate the distance between two points \( ({x}_{1}, {y}_{1}) \) and \( ({x}_{2}, {y}_{2}) \) we use the formula:

    \(d=\sqrt { ({{x}_{1}-{x}_{2} })^{ 2}+({y}_{1}-{y}_{2})^{2} }\)

    It does not matter which point we assign as point \(1\) and which we assign as point \(2\). Watch the next video to learn how to apply the distance formula.

     

    Midpoint formula

    To calculate the coordinate of the midpoint between two points \( ({x}_{1}, {y}_{1}) \) and \( ({x}_{2}, {y}_{2}) \) we use the formula:

    \(Midpoint=(\frac{{x}_{1}+{x}_{2}}{2}, \frac{{y}_{1}+{y}_{2}}{2})\)

    In the next video you will learn to apply the midpoint formula. 

    After watching both videos try the exercises that follow to test your knowledge on the distance and midpoint formulas.
