The only way I could think of doing this is checking for the angle of the object...then using trigonometry.

Yes. i could check for the angle between the object and the point by using atanfull(object x position - point x position,object z position - point z position). but i dont know what angles should be the result in order to know if i'm facing a point or not.

you could use a dummy object, hide it and position it at the main objects position
POINT OBJECT dummy,x#,y#,z#
then just check if all 3 angles from both objects are the same
