Distance between two points

Distance between two points

Given, Point A (x1, y1) and B (x2, y2) are two points on the cartesian plane

 

Using Pythagoras Theorem

c^2=a^2+b^2

AB^2=a^2+b^2

AB^2={(x_2-x_1)^2+(y_2-y_1)^2}

 |AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

 

Note:

The distance of a point A (x, y) from the  origin O (0, 0) is given by

|OA|=\sqrt{(x-0)^2+(y-0)^2}=\sqrt{x^2+y^2}
