Vertex A of triangle ABC.
Vertex B of triangle ABC
Vertex C of triangle ABC
Return ValueThe absolute value of the returned value is two times the area of the triangle ABC.
A positive return value indicates:
- Counterclockwise wrapping of the vertices.
- Vertex B lies to the right of line AC, looking from A toward C.
A negative value indicates:
- Clockwise wrapping of the vertices.
- Vertex B lies to the left of line AC, looking from A toward C.
A value of zero indicates that all points are collinear or represent the same point.
This is a low cost method.
