Find the area of a triangle using a determinant.

Grab a vertex and move it or move the sliders to change the coordinates of the vertices of the triangle.[br]The area is given by 1/2 of the absolute value of the determinant.[br]See if you can move the vertices so the value of the determinant becomes negative.
