# Distance Between Two Points

on . Posted in Geometry

The distance between two points using two given coordinate points.

## Distance between two points (2d) formula

$$\large{ d = \sqrt{ \left( x_2 - x_1 \right)^2 + \left( y_2 - y_1 \right)^2 } }$$
Symbol English Metric
$$\large{ d }$$ = distance $$\large{ in}$$ $$\large{ mm}$$
$$\large{ x_1 }$$ = x coordinate of first point $$\large{ in}$$ $$\large{ mm }$$
$$\large{ y_1 }$$ = x coordinate of first point  $$\large{ in}$$ $$\large{ mm }$$
$$\large{ x_2 }$$ = x coordinate of second point  $$\large{ in}$$  $$\large{ mm }$$
$$\large{ y_2 }$$ = x coordinate of second point  $$\large{ in}$$  $$\large{ mm }$$
