Calculate the area of a triangle given the coordinates of its three vertices using the coordinate geometry (shoelace) formula.
Calculate the area of a triangle given the coordinates of its three vertices using the coordinate geometry (shoelace) formula.
x-coordinate of the first vertex
y-coordinate of the first vertex
x-coordinate of the second vertex
y-coordinate of the second vertex
x-coordinate of the third vertex
y-coordinate of the third vertex
The shoelace formula computes the area of a polygon from vertex coordinates. For a triangle, it uses the three vertices and returns a non-negative area value.
