This calculator determines area of triangle, using its vertex coordinates in cartesian coordinate system. It was created by user request. The task is simple - first, determine lengths of edges, then use Heron formula to find area of triangle.
For Heron formula, see Calculator of area of a triangle using Hero's formula.

For cartesian coordinate systems the lengths are calculated as follows
$p=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2+(z_1-z_2)^2}$
For triangle on a plane let z coordinate to remain zero
