Computes the oriented area inside a triangle, arc or polygon.

oriented_area(Triangle)

Given a triangle, computes its area and the sign takes into account the orientation of its vertices.

oriented_area(Arc)

Given an arc, computes the area that encloses and the sign takes into account the orientation.

oriented_area(Polygon)

Given a polygon, computes the area that encloses and the sign takes into account the orientation of its vertices.
