Determinant(Double,Double,Double,Double,Double,Double) Method

In This Topic

Calculates the oriented area of the triangle formed by the given points.

Syntax

public static System.double Determinant( 
   System.double ax,
   System.double ay,
   System.double bx,
   System.double by,
   System.double cx,
   System.double cy
)

Parameters

ax: X coordinate of point a.
ay: Y coordinate of point a.
bx: X coordinate of point b.
by: Y coordinate of point b.
cx: X coordinate of point c.
cy: Y coordinate of point c.

Return Value

The oriented area of the triangle. If the returned value is positive -> the triplet is counter-clockwise oriented (CCW). If the returned value is negative -> the triplet is clockwise oriented (CW). If the returned value equals zero -> the triplet is collinear.

Remarks
