Description
This function determines whether a coordinate specified by (X, Y) can be found inside of the triangle specified by the points (X1, Y1), (X2, Y2) and (X3, Y3). If the coordinate is outside or on top of the triangle, False is returned.
Example
begin
if InTriangle(2, 2, 1, 1, 0, 3, 6, 3) then
WriteLn('The point can be found in the triangle')
else
WriteLn('The point is outside or on top of the triangle');
end.Output:
The point can be found in the triangle
